The HI3831F is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 50 tests.\u003c\/p\u003e\n\u003ch2\u003eFeatures at-a-glance\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eComplete setup \u003c\/strong\u003e\u003cul\u003e\u003cli\u003eAll required materials are included with the test kit,  such as the color comparison cube,  and reagent dropper bottles.\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eHigh resolution \u003c\/strong\u003e\u003cul\u003e\u003cli\u003eReadings from 0.0 to 2.5 mg\/L are determined to 0.5 mg\/L resolution.\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eReplacement reagents available\u003c\/strong\u003e\u003cul\u003e\u003cli\u003eThere is no need to buy a new kit when reagents are exhausted.

Chlorine (Cl\u003csub\u003e2\u003c\/sub\u003e) is a very desirable disinfectant because,  when mixed with pure water,  it reacts to form hypochlorous acid (HOCl) and hydrochloric acid (HCl). HOCl (free active chlorine) is the most effective form of chlorine for disinfection of pools,  spas,  and drinking water.\u003c\/p\u003e\n\u003cp\u003eDrinking water municipalities add elemental chlorine to the water supply as chlorine gas,  liquid sodium hypochlorite,  or dry calcium hypochlorite. In water these form free chlorine ions,  which destroy disease-causing pathogens,  reduce odor,  eliminate bacteria and help to remove unwanted elements. The USEPA requires that residual disinfectant is present in finished drinking water to ensure there is disinfectant available throughout the distribution system,  with chlorine acting as one of the disinfectants that provides said residual. However,  the EPA has also set a maximum contaminant level of 4.0 mg\/L for free chlorine due to potential health effects above this level.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI3831F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Free Chlorine Test Kit - HI3831F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Measurement Type\u003c\/td\u003e\n\u003ctd\u003e Colorimetric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Range\u003c\/td\u003e\n\u003ctd\u003e 0.0 to 2.5 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Resolution\u003c\/td\u003e\n\u003ctd\u003e 0.5 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Number of Tests\u003c\/td\u003e\n\u003ctd\u003e 50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChlorine Method\u003c\/td\u003e\n\u003ctd\u003e DPD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e 176 g (6.6 oz.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e 220 x 145 x 55 mm (8.7 x 5.7 x 2.1 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\u003cp\u003eHI3831F test kit comes with color comparison cube, 20 mL reagent 1, and 15 mL reagent 2.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/manuals.hannainst.com\/HI3831F\"\u003eFree Chlorine Test Kit - HI3831F\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871267881329,"sku":"HI3831F","price":2920.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3831f_2.jpg?v=1792645995","url":"https:\/\/hannainst.in\/products\/free-chlorine-test-kit-hi3831f","provider":"hanna","version":"1.0","type":"link"}
