The first step of this 2-step process is carried out in an aquarium by nitrifying bacteria. During this quick process, the ammonium levels drop while the nitrite levels increase. Since nitrite is just as harmful as ammonia, nitrite levels should be maintained at immeasurable levels. A mature biological filter should be able to keep nitrite levels low. Also, if tap water is to be used in an aquarium, it is recommended that it be tested for phosphate, as well as silicate, ammonia, nitrate, nitrite, pH, and alkalinity.\u003c\/p\u003e\n\u003cp\u003eThe HI764 Checker® Handheld Colorimeter bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate, while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. Hanna Checker®'s are accurate, affordable and easy to use.\u003c\/p\u003e\n\u003cp\u003eTo begin measurements, first, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Checker®, press the button and read the results. It's that easy.\u003c\/p\u003e\n\u003cp\u003eThe contoured style of these Checker®'s fit in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.\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\/checker1234.jpg\" alt=\"How to use Hanna Checker Handheld Colorimeter\" 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\u003ch5 style=\"margin-top: 0;\"\u003eFeatures at-a-glance:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eEasier to use and more accurate than chemical test kits\u003c\/li\u003e\n\u003cli\u003eDedicated to a single parameter\u003c\/li\u003e\n\u003cli\u003eSmall size, big convenience\u003c\/li\u003e\n\u003cli\u003eIdeal for: Water quality, Environmental, Plating, Education\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 48px;\"\u003e\u003ch2 style=\"margin-top: 0;\"\u003eVideo\u003c\/h2\u003e\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\u003eHI764\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eMarine Nitrite Ultra Low-Range Checker\u003csup\u003e®\u003c\/sup\u003e HC - HI764\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrite Range\u003c\/td\u003e\n\u003ctd\u003e0 to 200 ppb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrite Resolution\u003c\/td\u003e\n\u003ctd\u003e1 ppb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrite Accuracy\u003c\/td\u003e\n\u003ctd\u003e±10 ppb ±4% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNitrite Method\u003c\/td\u003e\n\u003ctd\u003eadaptation of the EPA Diazotization method 354.1.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Source\u003c\/td\u003e\n\u003ctd\u003eLED @ 525 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Detector\u003c\/td\u003e\n\u003ctd\u003esilicon photocell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Type\/Life\u003c\/td\u003e\n\u003ctd\u003e(1) 1.5V AAA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutomatic Shut-Off\u003c\/td\u003e\n\u003ctd\u003eafter two minutes of non-use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironment\u003c\/td\u003e\n\u003ctd\u003e0 to 50°C (32 to 122°F); RH max 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e64 g (2.25 oz.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e81.5mm x 61mm x 37.5mm (3.2 in. x 2.4 in. x 1.5”)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\u003cp\u003eHI764 Checker\u003csup\u003e®\u003c\/sup\u003e is supplied with (2) sample cuvettes with caps, nitrite ULR reagent starter kit for 6 tests (6 powder reagent packets), battery, instructions and quick start guide.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI764\" target=\"_blank\" rel=\"noopener\"\u003eMarine Nitrite Ultra Low-Range Checker\u003csup\u003e®\u003c\/sup\u003e HC - HI764\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871396135281,"sku":"HI764","price":6371.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi764-checkerhc-front.jpg?v=1792646392","url":"https:\/\/hannainst.in\/products\/marine-nitrite-ultra-low-range-checker-hc-hi764","provider":"hanna","version":"1.0","type":"link"}
