The conversion used is based on the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Since the majority of sugar in grape juice is fructose and glucose and not sucrose, the reading is sometimes referred to as \"Apparent Brix\".\u003c\/p\u003e\n\u003cp\u003eThe HI 96813 allows the user to tailor the instrument to their specific needs based on their experience, since no fixed conversion factor is universally applicable. The first conversion is based on the % Brix value and an adjustable conversion factor between 0.50 and 0.70 (0.55 is a common value).\u003c\/p\u003e\n\u003cp\u003ePotential alcohol (%V\/V) = (0.50 to 0.70) x % Brix\u003c\/p\u003e\n\u003cp\u003eOne drawback of the above equation is that it does not take into account the non-fermentable sugars and extract. A second equation is also available that takes these factors into account and can give a more accurate estimate of the alcohol content in the finished wine. This conversion is named \"C1\" on the meter, and uses the following equation:\u003c\/p\u003e\n\u003cp\u003ePotential Alcohol (%V\/V) = 0.059 x [(2.66 x °Oe) - 30] (C1)\u003cbr\u003e\n* 1°Oe is roughly equal 0.2% Brix\u003c\/p\u003e\n\u003ch4\u003eThe HI96813 is an easy to use tool for winemakers for measuring sugar and potential alcohol in grapes or must, in the field or in the lab.\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for wine sugar and potential alcohol analysis\u003c\/li\u003e\n\u003cli\u003eTemperature Compensation algorithms based on sucrose solution\u003c\/li\u003e\n\u003cli\u003e0 to 50 % Brix range with an accuracy of ±0.2% Brix\u003c\/li\u003e\n\u003cli\u003e0-25 % potential alcohol range with an accuracy of ±0.2% potential alcohol\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eMaking a Standard % Brix (Sucrose) Solution\u003c\/h4\u003e\n\u003cp\u003eTo make a Brix Solution, follow the procedure below:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePlace container (such as a glass vial or dropper bottle that has a cover) on an analytical balance.\u003c\/li\u003e\n\u003cli\u003eTare the balance.\u003c\/li\u003e\n\u003cli\u003eWeigh out X grams of high purity sucrose (CAS #: 57-50-1) directly into a beaker\u003c\/li\u003e\n\u003cli\u003eAdd distilled or deionized water to the beaker so the total weight of the solution is 100g.\u003c\/li\u003e\n\u003cli\u003eNote: Solutions above 65% may need to be vigorously stirred or shaken and heated in a water bath to roughly 40℃ (104℉).

Refractive index is a measurement of how light behaves as it passes through the sample. Depending on the sample's composition, light will refract and reflect differently. By measuring this activity with a linear image sensor, the sample's refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96813 uses an LED light, prism and lens to make measurement possible.\u003c\/p\u003e\n\u003cp\u003eVariations in temperature will affect the accuracy of refractometry readings, so the use of temperature compensation is highly recommended for reliable results. The HI96813 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book Standard for a percent by weight sucrose solution at 20℃. These compensation algorithms vary based on the parameter being measured.\u003c\/p\u003e\n\u003ch4\u003eFeatures at-a-glance:\u003c\/h4\u003e\n\u003cp\u003eOne-point calibration\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eCalibrate with distilled or deionized water\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eSmall sample size\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eSample size can be as small as 2 metric drops (100 μl)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eAutomatic Temperature Compensation (ATC)\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eSamples automatically compensated for temperature variations\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eQuick, accurate results\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eReadings are displayed in approximately 1.5 seconds\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eDual-level LCD\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eThe dual-level LCD displays measurement and temperature readings simultaneously\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eStainless steel sample well\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eEasy to clean and corrosion-resistant\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eBattery indicators\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eBattery percent level remaining at startup and low battery indicator\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eAutomatic shut-off\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eTo conserve battery life the meter shuts off automatically after three minutes of non-use\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eIP65 water resistant protection\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eWater resistant ABS plastic casing designed to perform under laboratory and field conditions.\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI96813\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eDigital Refractometer for % Brix and Potential Alcohol (% V\/V) Analysis in Wine, Must and Juice - HI96813\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSugar Content Range\u003c\/td\u003e\n\u003ctd\u003e0 to 50% Brix;
