It also used to improve the quality of drinking waters, as chlorine reacts with ammonia, iron, manganese, sulfide and some organic substances. Nevertheless, high amounts of chlorine will produce adverse effects, such as the formation of potentially carcinogenic compounds like chloroform or compounds with harmful effects to aquatic life like chloramines. Thus it essential that the proper amount of chlorine has been added in order to fulfill the primary purpose of disinfecting and to minimize any adverse effects.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSupplied with:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eColor comparison cube\u003c\/li\u003e \u003cli\u003eThree reagents (20 mL of reagent 1, 15 mL each of reagents 2 and 3).\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e \u003ctable border=\"1\" frame=\"border\" rules=\"all\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMethod\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eColorimetric\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eRange\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e0.0-2.5 mg\/L\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eSmallest Increment\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e0.5 mg\/L\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eChemical Method\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eDPD\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eNumber of Tests\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e50\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e205 g\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cp\u003e \u003c\/p\u003e \u003cdiv\u003e\u003c\/div\u003e","brand":"Hanna Instruments","offers":[{"title":"EA (1)","offer_id":51111228178747,"sku":"92-2804-04-EA","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/2041\/6571\/files\/92-2804-04.png?v=1784712545"},{"product_id":"comparator-dissolved-oxygen-0-40-ppb-chemetrics-inc-c-7540-non-regulated","title":"Comparator, Dissolved Oxygen, 0-40 ppb, Chemetrics, Inc., C-7540  Non-Regulated","description":"\u003cstrong\u003e\u003cspan style=\"font-size:\" small\u003eCHEMetrics™ Oxygen, Dissolved Comparator, 0-40 ppb, C-7540\u003c\/span\u003e\u003c\/strong\u003e\u003cspan style=\"font-size:\" small\u003eIncrements:\u003c\/span\u003e\u003cul\u003e\u003cli\u003e\u003cspan style=\"font-size:\" small\u003e0, 5, 10, 15, 20, 25, 30, 40 ppb\u003c\/span\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Chemetrics","offers":[{"title":"EA (1)","offer_id":51111232766267,"sku":"92-2813-20-EA","price":18.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/2041\/6571\/files\/92-2813-20.png?v=1784712690"},{"product_id":"comparator-dissolved-oxygen-0-0-1-0-ppm-chemetrics-inc-c-7501-non-regulated","title":"Comparator-Dissolved Oxygen, 0.0-1.0 ppm, Chemetrics, Inc., C-7501  Non-Regulated","description":"\u003cp\u003eThank you for visiting our website.
