These reagents follow the DPD (N,N-diethyl-p-phenylenediamine) method to determine free and total chlorine concentration.\u003c\/p\u003e \u003cp\u003eFor determination of free and total chlorine, the appropriate DPD powder reagent is added to a sample containing chlorine. The reaction between chlorine and the reagent causes a pink coloured complex to form; the greater the concentration, the deeper the colour. A Checker Disc is included for an accurate, side-by-side, visual analysis to determine free and total chlorine concentration. These reagents are designed to be used with low range samples that have an expected free and total chlorine range of 0.00 to 0.70 mg\/L (ppm) Cl\u003csub\u003e2\u003c\/sub\u003e and high range samples that have an expected range of 0.0 to 3.5 mg\/L (ppm) Cl\u003csub\u003e2\u003c\/sub\u003e.\u003c\/p\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.hannainstruments.co.uk\/modules\/teapotknowledgehub\/uploads\/manhi_38017-60880eaf4b730.pdf\" target=\"_blank\"\u003eHI-38017 Chlorine - Range (0.00-0.70 MG\/L)  (0.0-3.5 MG\/L) (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640058782069,"sku":"HI-38017-200","price":61.94,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/replacement-reagents-for-free-total-chlorine.jpg?v=1791580005","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-38017-200-replacement-reagents-for-free-total-chlorine","provider":"Test All Water","version":"1.0","type":"link"}
