Fluoride has beneficial effects on teeth at low concentrations in drinking water, but excessive exposure to fluoride in drinking water, or in combination with exposure to fluoride from other sources, can give rise to a number of adverse effects.\u003c\/p\u003e\n\u003cp\u003eWater fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay. Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. A 1994 World Health Organization expert committee suggested a level of fluoride from 0.5 to 1.0 mg\/L, depending on climate. Bottled water typically has unknown fluoride levels, and some domestic water filters remove some or all fluoride.\u003c\/p\u003e\n\u003cp\u003eDesigned as a more accurate alternative to chemical test kits, the HI739 provides quick, accurate results in four easy steps:\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\u003cp\u003e* To zero, mix 2 ml of Reagent A and 8 ml of Reagent B; gently invert 5 times, and wait 1 minute before inserting in the meter and pressing the button.\u003c\/p\u003e\n\u003ch5\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: Drinking Water, Environmental, Industrial\u003c\/li\u003e\n\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\u003eHI739\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eFluoride High-Range Checker\u003csup\u003e®\u003c\/sup\u003e HC - HI739\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFluoride Range\u003c\/td\u003e\n\u003ctd\u003e0.0 to 20.0 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFluoride Resolution\u003c\/td\u003e\n\u003ctd\u003e0.1 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFluoride Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.5 ppm ± 5% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFluoride Method\u003c\/td\u003e\n\u003ctd\u003eadaptation of the Standard Methods for the Examination of Water and Wastewater, 18\u003csup\u003eth\u003c\/sup\u003e edition, SPADNS method.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhotometer\/Colorimeter Light Source\u003c\/td\u003e\n\u003ctd\u003eLED @ 575 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 ten 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\u003eHI739 Checker\u003csup\u003e®\u003c\/sup\u003e is supplied with (2) sample cuvettes with caps, fluoride HR reagent starter kit for 15 tests (1 bottle of fluoride HR reagent A, 1 bottle of fluoride HR reagent B), (2) 1 mL syringe with tip, pipette, battery, and instructions.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI739\" target=\"_blank\" rel=\"noopener\"\u003eFluoride High-Range Checker\u003csup\u003e®\u003c\/sup\u003e HC - HI739\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871395545457,"sku":"HI739","price":6371.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi739-checkerhc-front.jpg?v=1792646384","url":"https:\/\/hannainst.in\/products\/fluoride-hr-checker-hc-hi739","provider":"hanna","version":"1.0","type":"link"}
