The HI3887 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 for free chlorine and 100 tests for pH.\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 cubes 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\n\u003cli\u003eFree chlorine readings from 0.0 to 2.5 mg\/L are determined to 0.5 mg\/L resolution.\u003c\/li\u003e\n\u003cli\u003epH readings from 6.0 to 8.5 pH are determined to 0.5 pH resolution.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch2\u003eSignificance of Use\u003c\/h2\u003e\n\u003cp\u003eChlorine is one of the most commonly used disinfectants for drinking water, wastewater, and water used for pools and spas. It can be added to in various forms including calcium hypochlorite, sodium hypochlorite, or in some instances, chlorine gas. When added to water, chlorine creates hypochlorous acid (HOCl) which dissociates into hypochlorite ion (OCl\u003csup\u003e-\u003c\/sup\u003e).\u003c\/p\u003e\n\u003cp\u003eHOCl ↔ H\u003csup\u003e+\u003c\/sup\u003e + OCl\u003csup\u003e-\u003c\/sup\u003e\u003cbr\u003e\nhypochlorous acid ↔ hydrogen ion + hypochlorite ion\u003c\/p\u003e\n\u003cp\u003eHOCl is the form of chlorine that acts as a stronger disinfectant as compared to OCl\u003csup\u003e-\u003c\/sup\u003e. To ensure the added chlorine is effective at sanitizing, the pH of the water must be taken into account. Around pH 7.5, HOCl and OCl\u003csup\u003e-\u003c\/sup\u003e are present in relatively equal amounts. Below pH 7.5, the equilibrium shifts to favor HOCl; above pH 7.5, the equilibrium shifts to favor OCl\u003csup\u003e-\u003c\/sup\u003e. Depending on the application, addition of chlorine is effective when added to water with a neutral or slightly acidic pH value.\u003c\/p\u003e\n\u003cp\u003eWhen chlorine is first added to water, it is available as free chlorine. The measurement of free chlorine signifies the amount available for disinfection. Once chlorine begins to sanitize bacteria and pathogens present in the water, it becomes combined chlorine; combined chlorine is no longer available to act as a disinfectant.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI3887\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eSwimming Pool Chemical Test Kit - HI3887\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Measurement Type\u003c\/td\u003e\n\u003ctd\u003ecolorimetric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.0 to 8.5 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Resolution\u003c\/td\u003e\n\u003ctd\u003e0.5 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Method\u003c\/td\u003e\n\u003ctd\u003epH indicator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Number of Tests\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Measurement Type\u003c\/td\u003e\n\u003ctd\u003ecolorimetric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Range\u003c\/td\u003e\n\u003ctd\u003e0.0 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\u003e0.5 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFree Chlorine Number of Tests\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChlorine Method\u003c\/td\u003e\n\u003ctd\u003eDPD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\u003cp\u003eHI3887 test kit comes with color comparison cubes (2), 20 mL reagent 1, 15 mL reagent 2, 25 mL HI 3881-0 pH 6.0-8.5 reagent.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI3887\" target=\"_blank\" rel=\"noopener\"\u003eSwimming Pool Chemical Test Kit - HI3887\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871274991985,"sku":"HI3887","price":5835.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3887_2017.jpg?v=1792646021","url":"https:\/\/hannainst.in\/products\/swimming-pool-chemical-test-kit-hi3887","provider":"hanna","version":"1.0","type":"link"}
