DPD method. Range (0.0-3.5 mg\/L).\u003c\/p\u003e\u003cp\u003eThe HI-3875 free chlorine, medium range test kit is equipped with all you need to determine free chlorine levels in water. Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds resulting in diminished disinfecting capabilities compared with free chlorine. These chlorine compounds together with chloramines form combined chlorine. Combined chlorine and excess free chlorine together result in total chlorine. While free chlorine has a much higher disinfectant potential, combined chlorine has a much higher stability and has a lesser volatility. There should be sufficient levels of unreacted free chlorine for adequate disinfection, but not so much as to become harmful.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eOrder information\u003c\/b\u003e\u003cbr\u003e The HI-3875 free chlorine, medium range test kit comes supplied with; HI-93701-0 free chlorine reagents (100 pack), 500mL deionised water, checker disc, glass vials with caps (2) and 3mL plastic pipette.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eChecker Disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0.0-3.5 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSmallest Increment\u003c\/td\u003e\n\u003ctd\u003e0.1 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChemical Method\u003c\/td\u003e\n\u003ctd\u003eDPD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Tests\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e984 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.hannainstruments.co.uk\/modules\/teapotknowledgehub\/uploads\/istr_3875r2_07_05-6087de73eadd2.pdf\" target=\"_blank\"\u003eHI-3875 Free Chlorine Test Kit (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640060944757,"sku":"HI-3875","price":76.76,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/chlorine-test-kit.jpg?v=1791580083","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-3875-free-chlorine-test-kit","provider":"Test All Water","version":"1.0","type":"link"}
