Bromine,  chlorine,  and iodine determination use the DPD method; iron determination uses an adaptation of the TPTZ method; pH determination uses the phenol red method; cyanuric acid determination uses an adaptation of the turbidimetric method. The reagents are in powder and liquid form depending on the parameter being tested.\u003c\/p\u003e\n\u003cp\u003eChlorine is the most commonly used water disinfectant used by homeowners,  hotels,  and commercial businesses. In swimming pools,  spas,  and similar applications,  cyanuric acid helps to stabilize chlorine and prevent its breakdown,  especially in sunlight. Frequent testing of both cyanuric acid and pH helps to minimize chlorine consumption. The disinfecting properties of bromine and iodine have led to their use as alternatives to chlorine. One of the most common applications of iodine is poultry industry process water,  while bromine is used in sanitization of cooling towers and pools and spas.\u003c\/p\u003e\n\u003cp\u003eWhen the appropriate reagent is added to the sample,  it will display a color change; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For determination of all six parameters,  a narrow band interference filter at 525 nm (green) allows only green light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1p00mgl-Certificate-Value-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Setup-Screen.jpg\" alt=\"method option\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Measure-Tutorial-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1c00min-Reaction-Time-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97101 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97101 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

multiple methods within one meter. Bromine,  chlorine,  and iodine determination use the DPD method; iron determination uses an adaptation of the TPTZ method; pH determination uses the phenol red method; cyanuric acid determination uses an adaptation of the turbidimetric method. The reagents are in powder and liquid form depending on the parameter being tested.\u003c\/p\u003e\n\u003cp\u003eChlorine is the most commonly used water disinfectant used by homeowners,  hotels,  and commercial businesses. In swimming pools,  spas,  and similar applications,  cyanuric acid helps to stabilize chlorine and prevent its breakdown,  especially in sunlight. Frequent testing of both cyanuric acid and pH helps to minimize chlorine consumption. The disinfecting properties of bromine and iodine have led to their use as alternatives to chlorine. One of the most common applications of iodine is poultry industry process water,  while bromine is used in sanitization of cooling towers and pools and spas.\u003c\/p\u003e\n\u003cp\u003eWhen the appropriate reagent is added to the sample,  it will display a color change; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For determination of all six parameters,  a narrow band interference filter at 525 nm (green) allows only green light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1p00mgl-Certificate-Value-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Setup-Screen.jpg\" alt=\"method option\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Measure-Tutorial-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1c00min-Reaction-Time-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97101 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97101 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

chemical used by many due to is disinfection properties. Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6 the predominate form is hypochlorous acid (HOCl) while at pH greater than 7.6 the hypochlorite (OCl\u003csup\u003e-\u003c\/sup\u003e) form becomes predominate. This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both the free chlorine and combined chlorine present. Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools combined chlorine that we can smell and is irritating to the eyes. The free chlorine measurement is subtracted from the total chlorine measurement in order to know how much combined chlorine is present. HI97104 is designed to measure swimming pool key water quality paramters. These parameters,  in addition to chlorine,  are pH,  alkalinity,  and cyanuric acid.\u003c\/p\u003e\n\u003cp\u003eThe HI97104 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement. This compact,  waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically,  step by step,  in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods,  reviewing GLP data,  recalling the last 50 measurements,  and customizing the meter to user preferences\u003c\/p\u003e\n\u003cp\u003eHI97104 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75\") by 37 mm (1.6\") and is backlit for easy viewing under all conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003cul\u003e\u003cli\u003eLED that generates very little heat\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm and offers 25% increase in light efficiency.\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: stretch; text-align: left;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Cal_Check.jpg\" alt=\"CAL Check HI97700\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance,  GLP for last calibration date,  setup options and the ability to see all accessories used with the meter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: stretch; text-align: left;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"tutorial mode HI97104\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eWhen enabled,  the tutorial mode will guide the user step by step through the measurement process .\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: stretch; text-align: left;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" width=\"300\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMethod Options\u003c\/h4\u003e\n\u003cp\u003eChoice of powder or economical liquid reagents for chlorin measurments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97104 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97104 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6 the predominate form is hypochlorous acid (HOCl) while at pH greater than 7.6 the hypochlorite (OCl\u003csup\u003e-\u003c\/sup\u003e) form becomes predominate. This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both the free chlorine and combined chlorine present. Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools combined chlorine that we can smell and is irritating to the eyes. The free chlorine measurement is subtracted from the total chlorine measurement in order to know how much combined chlorine is present. HI97104 is designed to measure swimming pool key water quality paramters. These parameters,  in addition to chlorine,  are pH,  alkalinity,  and cyanuric acid.\u003c\/p\u003e\n\u003cp\u003eThe HI97104 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement.

The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods,  reviewing GLP data,  recalling the last 50 measurements,  and customizing the meter to user preferences\u003c\/p\u003e\n\u003cp\u003eHI97104 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries.

Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6 hypochlorous acid (HOCl) is the predominate form found while at pH greater than 7.6 the hypochlorite (OCl-) form becomes predominate. This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both the free chlorine and combined chlorine present. Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools, combined chlorine that we can smell, is irritating to the eyes. A free chlorine measurement is subtracted from a total chlorine measurement to determine how much combined chlorine is present.\u003c\/p\u003e\n\u003cp\u003eAlkalinity is also a very important parameter in monitoring swimming pool water chemistry. Alkalinity is the buffering capacity of a solution to resist change from an acid or base. Chlorine can also be a base that will increase the pH of the water as it is added to it. Having a sufficient level of alkalinity helps to buffer against the pH so that it takes more over time in order to cause a pH change.\u003c\/p\u003e\n\u003cp\u003eCyanuric acid is often added to a swimming pool to prevent the loss of chlorine to sunlight. Cyanuric acid is commonly found in dry chlorine such as trichloroisocyanurate (trichlor). This form can be purchased as a solid “puck” and placed in flotation devices to erode slowly into the water. Maintaining the proper level of cyanuric acid will increase the life of chlorine in the pool. Cyanuric acid will build up overtime as more chemical is added. Unfortunately, having too much will decease the Redox (ORP) potential that is effective at killing the bacteria in the pool. For this reason cyanuric acid should be measured for pools that are using it as a stabilizer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Note: \u003c\/strong\u003eChlorine by DPD chemical measurement is preferred over ORP measurements due to the masking of the oxidation potential from chlorine and other oxidizers when using cyanuric acid (isocyanurate containing sanitizers) as a stabilizer. It will be possible to obtain a 625 -650 mV ORP reading when using cyanuric acid.\u003c\/p\u003e\n\u003cp\u003eHI971044 allows any user to measure these key swimming pool water quality parameters with laboratory grade accuracy.

Copper may also be present in natural water and effluents due to widespread use to control biological growths in reservoirs and distribution pipes.The HI96702 uses an adaptation of the USEPA approved bicinchoninate method to measure copper concentrations of less than 5.00 mg\/L (ppm). When the reagent is added to samples containing copper, the sample will turn a purple hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complimentary color, and the emitted radiation is dependent upon concentration. For higher levels of copper, a narrow band interference filter at 575 nm (yellow-green) allows only yellow- green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003cp\u003eThis innovative optical system offers superior performance in accuracy, repeatability, and required time to perform a measurement.

Copper may also be present in natural water and effluents due to widespread use to control biological growths in reservoirs and distribution pipes.The HI96702 uses an adaptation of the USEPA approved bicinchoninate method to measure copper concentrations of less than 5.00 mg\/L (ppm). When the reagent is added to samples containing copper, the sample will turn a purple hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complimentary color, and the emitted radiation is dependent upon concentration. For higher levels of copper, a narrow band interference filter at 575 nm (yellow-green) allows only yellow- green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003cp\u003eThis innovative optical system offers superior performance in accuracy, repeatability, and required time to perform a measurement.

Hydrazine reacts with dissolved oxygen to yield nitrogen and water; this is an advantage over the sulfite treatment because it does not produce any dissolved solids in the boiled water. Hydrazine is also used as an energy source in fuel elements,  as a reducing agent for metal recovery,  and as an intermediate in the production of insecticides,  herbicides,  pharmaceuticals,  and many other chemical products.\u003c\/p\u003e\n\u003cp\u003eThe HI97704 uses an Adaptation of the Standard Methods for the ASTM Manual of Water and Environmental Technology,  Method D1385,  p-Dimethylaminobenzaldehyde method to measure hydrazine concentrations up to 400 µg\/L (ppb). When the reagent is added to samples containing hydrazine,  the sample turns a yellow hue; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For hydrazine determination,  a narrow band interference filter at 466 nm allows only blue light to be emitted and passed through the sample cuvette.\u003c\/p\u003e\n\u003cp\u003eThis innovative optical system offers superior performance in accuracy,  repeatability,  and required time to perform a measurement.

Hydrazine reacts with dissolved oxygen to yield nitrogen and water; this is an advantage over the sulfite treatment because it does not produce any dissolved solids in the boiled water. Hydrazine is also used as an energy source in fuel elements,  as a reducing agent for metal recovery,  and as an intermediate in the production of insecticides,  herbicides,  pharmaceuticals,  and many other chemical products.\u003c\/p\u003e\n\u003cp\u003eThe HI97704 uses an Adaptation of the Standard Methods for the ASTM Manual of Water and Environmental Technology,  Method D1385,  p-Dimethylaminobenzaldehyde method to measure hydrazine concentrations up to 400 µg\/L (ppb). When the reagent is added to samples containing hydrazine,  the sample turns a yellow hue; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For hydrazine determination,  a narrow band interference filter at 466 nm allows only blue light to be emitted and passed through the sample cuvette.\u003c\/p\u003e\n\u003cp\u003eThis innovative optical system offers superior performance in accuracy,  repeatability,  and required time to perform a measurement.

Silica is only slightly soluble in water and can be found as ionic silica,  silicates,  or colloidal or suspended particles. The solubility of silica is highly dependent on pH,  temperature,  and pressure,  and in unfavorable conditions forms deposits or scale. Silica’s presence in industrial applications,  particularly high-pressure turbines,  is undesirable because of the scaling caused by the elevated temperature and pressure. Heating systems and reverse osmosis plants also require monitoring of silica to ensure process efficiency.\u003c\/p\u003e\n\u003cp\u003eThe HI97705 uses an adaptation of the ASTM Method D859 (Heteropoly Molybdenum Blue Method) to measure silica concentrations below 2.00 mg\/L (ppm). When the reagent is added to samples containing silica,  the sample will turn a blue hue,  the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For low-range silica determination,  a narrow band interference filter at 610 nm allows only orange light to be detected by the silicon photodetector and omits all other visible light emitted from the LED. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases. Using a pre-programmed curve a result is then displayed.\u003c\/p\u003e\n\u003cp\u003eThe HI97705 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement. This compact,  waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically,  step by step,  in performing a measurement. The use of a backlit dot matrix LCD allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure,  reviewing GLP data,  recalling the last 50 measurements,  and customizing the meter to user preferences.\u003c\/p\u003e\n\u003cp\u003eHI97705 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortably in the hand for use in the field or on a table for benchtop use. The LCD is backlit for easy viewing under all conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1p00mgl-Certificate-Value-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Setup-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI97705-Chemical-Form-Screen.jpg\" alt=\"method option\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Measure-Tutorial-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1c00min-Reaction-Time-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97705 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97705 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

Silica is only slightly soluble in water and can be found as ionic silica,  silicates,  or colloidal or suspended particles. The solubility of silica is highly dependent on pH,  temperature,  and pressure,  and in unfavorable conditions forms deposits or scale. Silica’s presence in industrial applications,  particularly high-pressure turbines,  is undesirable because of the scaling caused by the elevated temperature and pressure. Heating systems and reverse osmosis plants also require monitoring of silica to ensure process efficiency.\u003c\/p\u003e\n\u003cp\u003eThe HI97705 uses an adaptation of the ASTM Method D859 (Heteropoly Molybdenum Blue Method) to measure silica concentrations below 2.00 mg\/L (ppm). When the reagent is added to samples containing silica,  the sample will turn a blue hue,  the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For low-range silica determination,  a narrow band interference filter at 610 nm allows only orange light to be detected by the silicon photodetector and omits all other visible light emitted from the LED. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases. Using a pre-programmed curve a result is then displayed.\u003c\/p\u003e\n\u003cp\u003eThe HI97705 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement. This compact,  waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically,  step by step,  in performing a measurement. The use of a backlit dot matrix LCD allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure,  reviewing GLP data,  recalling the last 50 measurements,  and customizing the meter to user preferences.\u003c\/p\u003e\n\u003cp\u003eHI97705 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortably in the hand for use in the field or on a table for benchtop use. The LCD is backlit for easy viewing under all conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1p00mgl-Certificate-Value-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Setup-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI97705-Chemical-Form-Screen.jpg\" alt=\"method option\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Measure-Tutorial-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/1c00min-Reaction-Time-Screen.jpg\" alt=\"\" width=\"350\" height=\"202\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97705 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97705 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

However, large concentrations of Phosphorus cause excessive microorganism and algae growth and corrosive to piping in high concentrations.\u003c\/p\u003e\n\u003cp\u003eThe HI97706 uses an adaptation of the Standard Method for the Examination of Water and Wastewater, 23rd edition, amino acid method to measure phosphorus concentrations of up to 15.0 mg\/L (ppm). When the reagent is added to samples containing Phosphorus, the sample turns a blue hue; the greater the concentration of phosphorus, the deeper the color. The associated change is colorimetrically analyzed according to the Beer-Lambert Law which states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For Phosphorus determination, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, and transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex;

However, large concentrations of Phosphorus cause excessive microorganism and algae growth and corrosive to piping in high concentrations.\u003c\/p\u003e\n\u003cp\u003eThe HI97706 uses an adaptation of the Standard Method for the Examination of Water and Wastewater, 23rd edition, amino acid method to measure phosphorus concentrations of up to 15.0 mg\/L (ppm). When the reagent is added to samples containing Phosphorus, the sample turns a blue hue; the greater the concentration of phosphorus, the deeper the color. The associated change is colorimetrically analyzed according to the Beer-Lambert Law which states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For Phosphorus determination, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, and transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex;

In cooling towers,  however,  an adequate amount of nitrites is necessary to prevent corrosion. In high concentrations,  they can be harmful to the environment and to humans. They are,  therefore,  normally monitored to verify the quality of water for domestic use,  as well as lakes and ponds.\u003c\/p\u003e\n\u003cp\u003eNitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water,  or even originate in industrial waste directly.

When the reagent is added to samples containing nitrite,  the sample will turn a pink tint; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complimentary color,  and the emitted radiation is dependent upon concentration. For low levels of nitrite,  a narrow band interference filter at 466 nm. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97707 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97707 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

In cooling towers,  however,  an adequate amount of nitrites is necessary to prevent corrosion. In high concentrations,  they can be harmful to the environment and to humans. They are,  therefore,  normally monitored to verify the quality of water for domestic use,  as well as lakes and ponds.\u003c\/p\u003e\n\u003cp\u003eNitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water,  or even originate in industrial waste directly. They must not be present in drinking water.\u003c\/p\u003e\n\u003cp\u003eThe HI97707 uses an adaptation of the EPA approved Diazotization method 354.1 to measure nitrite concentrations in the 0to 600 µg\/L (ppb) range. When the reagent is added to samples containing nitrite,  the sample will turn a pink tint; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complimentary color,  and the emitted radiation is dependent upon concentration. For low levels of nitrite,  a narrow band interference filter at 466 nm. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97707 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97707 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

In cooling towers, however, an adequate amount of nitrites is necessary to prevent corrosion. In high concentrations, they can be harmful to the environment and to humans. They are, therefore, normally monitored to verify the quality of water for domestic use, as well as lakes and ponds.\u003c\/p\u003e\n\u003cp\u003eNitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water, or even originate in industrial waste directly. They must not be present in drinking water.\u003c\/p\u003e\n\u003cp\u003eThe HI97708 uses an adaptation of the ferrous sulfate method to measure nitrate up to 150 mg\/L (ppm). When the reagent is added to samples containing nitrite, the sample will turn a pink tint; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complimentary color, and the emitted radiation is dependent upon concentration. For low levels of nitrite, a narrow band interference filter at 575 nm. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex;

In cooling towers,  however,  an adequate amount of nitrites is necessary to prevent corrosion. In high concentrations,  they can be harmful to the environment and to humans. They are,  therefore,  normally monitored to verify the quality of water for domestic use,  as well as lakes and ponds.\u003c\/p\u003e\n\u003cp\u003eNitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water,  or even originate in industrial waste directly. They must not be present in drinking water.\u003c\/p\u003e\n\u003cp\u003eThe HI97708 uses an adaptation of the ferrous sulfate method to measure nitrate up to 150 mg\/L (ppm). When the reagent is added to samples containing nitrite,  the sample will turn a pink tint; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complimentary color,  and the emitted radiation is dependent upon concentration. For low levels of nitrite,  a narrow band interference filter at 575 nm. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eSetup options for meter personalization include date and time format,  language,  and enabling the tutorial mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97708 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97708 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

Manganese salts are also used in iron alloys (steel manufacturing) and non-iron alloys as it improves their corrosion resistance and hardness.\u003c\/p\u003e\n\u003cp\u003eThe HI97709 meter measures the manganese content in water samples up to 20.0 mg\/L (ppm). The method is an adaptation of the Standard Methods for the Examination of Water and Wastewater, 23rd Edition, Periodate Method. When the reagent is added to samples containing manganese, the sample will turn a violet hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For manganese determination, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003cp\u003eThis innovative optical system offers superior performance in accuracy, repeatability, and required time to perform a measurement.

Manganese salts are also used in iron alloys (steel manufacturing) and non-iron alloys as it improves their corrosion resistance and hardness.\u003c\/p\u003e\n\u003cp\u003eThe HI97709 meter measures the manganese content in water samples up to 20.0 mg\/L (ppm). The method is an adaptation of the Standard Methods for the Examination of Water and Wastewater,  23rd Edition,  Periodate Method. When the reagent is added to samples containing manganese,  the sample will turn a violet hue; the greater the concentration,  the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For manganese determination,  a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003cp\u003eThis innovative optical system offers superior performance in accuracy,  repeatability,  and required time to perform a measurement.

Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6 the predominate form is hypochlorous acid (HOCl) while at pH greater than 7.6 the hypochlorite (OCl\u003csup\u003e-\u003c\/sup\u003e) form becomes predominate. This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both the free chlorine and combined chlorine present. Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools combined chlorine that we can smell and is irritating to the eyes. The free chlorine measurement is subtracted from the total chlorine measurement in order to know how much combined chlorine is present.

Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6 the predominate form is hypochlorous acid (HOCl) while at pH greater than 7.6 the hypochlorite (OCl\u003csup\u003e-\u003c\/sup\u003e) form becomes predominate.  This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both the free chlorine and combined chlorine present. Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools combined chlorine that we can smell and is irritating to the eyes. The free chlorine measurement is subtracted from the total chlorine measurement in order to know how much combined chlorine is present. HI97710 is designed to measure pH and low levels of free and total chlorine in water up to 5.00 mg\/L (ppm).\u003c\/p\u003e\n\u003cp\u003eThe HI97710 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement.

It can be found in both water for drinking and for boilers\/cooling towers. The HI97713 uses an ascorbic acid method in which orthophosphate reacts with molybdate in an acid solution to form a yellow-colored phosphomolybdate complex. The phosphomolybdate complex is then reduced by ascorbic acid and as a result a blue color is produced that is proportional to the concentration of phosphate in the sample. The ascorbic acid method is ideal for measuring samples with a low concentration of phosphate.

It can be found in both water for drinking and for boilers\/cooling towers. The HI97713 uses an ascorbic acid method in which orthophosphate reacts with molybdate in an acid solution to form a yellow-colored phosphomolybdate complex. The phosphomolybdate complex is then reduced by ascorbic acid and as a result a blue color is produced that is proportional to the concentration of phosphate in the sample. The ascorbic acid method is ideal for measuring samples with a low concentration of phosphate.

Originating in water primarily from metallurgical and galvanic industrial plants, cyanide is highly toxic to the human nervous system.\u003c\/p\u003e\n\u003cp\u003eThe HI97714 uses an adaptation of the Pyridine-Pyrazolone method to measure cyanide concentrations up to 0.200 mg\/L (ppm). When the pyridine-based reagent is added to samples containing cyanide, the sample turns a blue hue; the greater the concentration, the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For cyanide determination, a narrow band interference filter at 610 nm allows only orange light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance of the light hitting the silicon photodetector decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary, recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97714 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97714 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

Originating in water primarily from metallurgical and galvanic industrial plants,  cyanide is highly toxic to the human nervous system.\u003c\/p\u003e\n\u003cp\u003eThe HI97714 uses an adaptation of the Pyridine-Pyrazolone method to measure cyanide concentrations up to 0.200 mg\/L (ppm). When the pyridine-based reagent is added to samples containing cyanide,  the sample turns a blue hue; the greater the concentration,  the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For cyanide determination,  a narrow band interference filter at 610 nm allows only orange light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance of the light hitting the silicon photodetector decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97714 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97714 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

Ammonia is also a commonly found in fertilizer and used as a nitrogen source for plant growth. It is effective in cleaning chemical and can be found in glass and floor cleaners. Ammonia exists in two forms. One is the ionized form ammonium (NH\u003csub\u003e4\u003c\/sub\u003e\u003csup\u003e+\u003c\/sup\u003e) and the other is the gaseous form ammonia (NH\u003csub\u003e3\u003c\/sub\u003e).  The relationship in which form is present is based on the pH of the solution with ammonium becoming more predominate at pH's less than 8. Since most naturally occurring water is pH 8 or less,  ammonium is the most common form present.  For aquatic life,  as the pH increases this can be lethal as the ammonium is converted to ammonia,  which is more toxic since it can diffuse back into the animal. In wastewater effluent the concentration is lower than the influence due to the nitrification process that takes place in the aeration basin. Using the Nessler method,  the HI 97700 is designed to measure ammonia in the Medium Range at levels from 0 to 10.00 mg\/L ammonia - nitrogen. The results can be displayed as ammonia or ammonium as well.\u003c\/p\u003e\n\u003cp\u003eThe HI97715 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement. This compact,  waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically,  step by step,  in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure,  reviewing GLP data,  recalling the last 50 measurements,  and customizing the meter to user preferences.\u003c\/p\u003e\n\u003cp\u003eHI97715 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries.

Ammonia is also a commonly found in fertilizer and used as a nitrogen source for plant growth. It is effective in cleaning chemical and can be found in glass and floor cleaners. Ammonia exists in two forms. One is the ionized form ammonium (NH\u003csub\u003e4\u003c\/sub\u003e\u003csup\u003e+\u003c\/sup\u003e) and the other is the gaseous form ammonia (NH\u003csub\u003e3\u003c\/sub\u003e).  The relationship in which form is present is based on the pH of the solution with ammonium becoming more predominate at pH's less than 8. Since most naturally occurring water is pH 8 or less,  ammonium is the most common form present.  For aquatic life,  as the pH increases this can be lethal as the ammonium is converted to ammonia,  which is more toxic since it can diffuse back into the animal. In wastewater effluent the concentration is lower than the influence due to the nitrification process that takes place in the aeration basin. Using the Nessler method,  the HI 97700 is designed to measure ammonia in the Medium Range at levels from 0 to 10.00 mg\/L ammonia - nitrogen. The results can be displayed as ammonia or ammonium as well.\u003c\/p\u003e\n\u003cp\u003eThe HI97715 has an innovative optical system that offers superior performance in accuracy,  repeatability,  and the short amount of time it takes to perform a measurement. This compact,  waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically,  step by step,  in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure,  reviewing GLP data,  recalling the last 50 measurements,  and customizing the meter to user preferences.\u003c\/p\u003e\n\u003cp\u003eHI97715 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries.

Due to its stability at higher temperatures and higher pH levels, bromine is most often used in sanitization of pools and spas, and cooling towers.\u003c\/p\u003e\n\u003cp\u003eThe HI97716 uses an adaptation of the DPD method per Standard Methods for the Examination of Water and Wastewater, 23rd Edition, to measure bromine concentrations up to 10.00 mg\/L (ppm). When the DPD reagent is added to samples containing bromine, the sample turns a pink hue; the greater the concentration, the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For bromine determination, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex;

Due to its stability at higher temperatures and higher pH levels,  bromine is most often used in sanitization of pools and spas,  and cooling towers.\u003c\/p\u003e\n\u003cp\u003eThe HI97716 uses an adaptation of the DPD method per Standard Methods for the Examination of Water and Wastewater,  23rd Edition,  to measure bromine concentrations up to 10.00 mg\/L (ppm). When the DPD reagent is added to samples containing bromine,  the sample turns a pink hue; the greater the concentration,  the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For bromine determination,  a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97716 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97716 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/2c30min-Reaction-Time-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eReaction Timer\u003c\/h4\u003e\n\u003cp\u003eBuilt-in reaction timer that ensures consistency amongst multiple users.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97717 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97717 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

Unlike chlorinated pools, water treated with iodine decreases eye irritation among swimmers and provides a level of disinfection more stable to adverse conditions. However, its toxic and corrosive properties, and the difficulties of dissolving it in water have limited its widespread acceptance. One of the most common applications of iodine is in poultry industry process water.\u003c\/p\u003e\n\u003cp\u003eThe HI97718 uses an adaptation of the Standard Methods for the Examination of Water and Wastewater, 23rd Edition, DPD method to measure iodine concentrations up to 12.5 mg\/L (ppm). When added to a sample containing iodine, the DPD reagent will react to turn the sample a pink hue; the greater the concentration, the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For iodine, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette.

Unlike chlorinated pools, water treated with iodine decreases eye irritation among swimmers and provides a level of disinfection more stable to adverse conditions. However, its toxic and corrosive properties, and the difficulties of dissolving it in water have limited its widespread acceptance. One of the most common applications of iodine is in poultry industry process water.\u003c\/p\u003e\n\u003cp\u003eThe HI97718 uses an adaptation of the Standard Methods for the Examination of Water and Wastewater, 23rd Edition, DPD method to measure iodine concentrations up to 12.5 mg\/L (ppm). When added to a sample containing iodine, the DPD reagent will react to turn the sample a pink hue; the greater the concentration, the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For iodine, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, the absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex;

The concentration of these salts determines the water hardness, which can be expressed in calcium carbonate or magnesium carbonate. The sum of these two represents the total hardness level. In addition, water hardness is also related to the phenomenon of pipe rusting in water heating and cooling systems, reverse osmosis, and demineralization plants.\u003c\/p\u003e\n\u003cp\u003eThe HI97719 uses an adaptation of the Standard Methods for the Examination of Water and Wastewater, 23rd Edition, EDTA colorimetric method to measure magnesium hardness concentrations up to 2.00 mg\/L (ppm). When the reagent is added to samples containing magnesium salts, the sample will turn a violet hue; the greater the concentration, the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For magnesium hardness determination, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003cul\u003e\u003cli\u003e\u003cul\u003e\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\u003c\/ul\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e\u003cul\u003e\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\u003c\/ul\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e\u003cul\u003e\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\u003c\/ul\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary, recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97719 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97719 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

The concentration of these salts determines the water hardness,  which can be expressed in calcium carbonate or magnesium carbonate. The sum of these two represents the total hardness level. In addition,  water hardness is also related to the phenomenon of pipe rusting in water heating and cooling systems,  reverse osmosis,  and demineralization plants.\u003c\/p\u003e\n\u003cp\u003eThe HI97719 uses an adaptation of the Standard Methods for the Examination of Water and Wastewater,  23rd Edition,  EDTA colorimetric method to measure magnesium hardness concentrations up to 2.00 mg\/L (ppm). When the reagent is added to samples containing magnesium salts,  the sample will turn a violet hue; the greater the concentration,  the deeper the color. The associated color change is colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color,  and the emitted radiation is dependent upon concentration. For magnesium hardness determination,  a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases,  absorbance of the specific wavelength of light also increases,  while transmittance decreases.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/PHOTOMETER-OPTICAL-SYSTEM.jpg\" alt=\"photometer optical system\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to ±1 nm.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"margin: 0 0 24px; text-align: center;\"\u003eOn-Screen Features\u003c\/h2\u003e\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/0p400mgl-Certificate-Value-Screen.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eCAL Check\u003c\/h4\u003e\n\u003cp\u003eAdvanced features including CAL-Check to verify performance and if necessary,  recalibrate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eMultiple Chemical Forms\u003c\/h4\u003e\n\u003cp\u003eResults can be displayed in multiple chemical forms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/Method_Selection.jpg\" alt=\"method option\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eSetup Options\u003c\/h4\u003e\n\u003cp\u003eBacklit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: center; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/tutorial.jpg\" alt=\"\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eTutorial Mode\u003c\/h4\u003e\n\u003cp\u003eTutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eHI97719 FEATURES\/BENEFITS:\u003c\/h4\u003e\n\u003ch5\u003eStable Light Source:\u003c\/h5\u003e\n\u003cul\u003e\u003cli\u003eThe internal reference system of the HI97719 photometer compensates for any drifts due to power fluctuations or ambient temperature changes.

The HI97721 uses an adaptation of method 3500-Fe B, the phenanthroline method, from Standard Methods for the Examination of Water and Wastewater, 23rd Edition.

The solution is then treated with 1, 10-phenanthroline at a pH of 3.2 to 3.3. Three molecules of phenanthroline then react with one ferrous iron atom to form a complex with an orange color. The intensity of the color is directly proportional to the amount of ferrous iron in the sample. The phenanthroline method is ideal for measuring samples with a high concentration of iron.
