Chlorine present in water binds with bacteria, leaving only part of the original quantity (free chlorine) to continue its disinfecting action.\u003c\/p\u003e\u003ch3\u003eTotal Chlorine test kit, low, medium and high range\u003c\/h3\u003e \u003cp\u003e\u003cbr\u003e\u003cbr\u003e The HI 38020 free and total chlorine test kit, low, medium and high range is equipped with all you need to determine free chlorine levels in water.\u003cbr\u003e\u003cbr\u003e 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.\u003cbr\u003e\u003cbr\u003e \u003cb\u003eOrder information\u003c\/b\u003e\u003cbr\u003e The HI 38020 free and total chlorine, low, medium and high range test kit comes supplied with; HI 93701-0 free chlorine reagent, HI 93711-0 total chlorine reagent, demineraliser bottle with filter cap for 12L, checker disc, glass vials with caps (2) and 3 mL 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\u003e0.00-0.70 mg\/L 0.0-3.5 mg\/L 0.0-10.0 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSmallest Increment\u003c\/td\u003e\n\u003ctd\u003e0.02 mg\/L 0.1 mg\/L 0.5 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\u003e200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e688 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\/manhi_38020-608809eb492bd.pdf\" target=\"_blank\"\u003eHI-38020 Chlorine - Range (0.00-0.70 Mg\/L) (0.0-3.5 Mg\/L) (0.0-10.0 Mg\/L) (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640058880373,"sku":"HI-38020","price":167.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/chlorine-range-0-00-0-70-mg-l-0-0-3-5-mg-l-0-0-10-0-mg-l.jpg?v=1791580010","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-38020-chlorine-range-0-00-0-70-mg-l-0-0-3-5-mg-l-0-0-10-0-mg-l","provider":"Test All Water","version":"1.0","type":"link"}
