The HI3812 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 100 tests.\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 sample beaker, plastic pipette, 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\u003eReadings from 0.0 to 30.0 mg\/L are determined to 0.3 mg\/L resolution.\u003c\/li\u003e\n\u003cli\u003eReadings from 0 to 300 mg\/L are determined to 3 mg\/L resolution.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eReplacement reagents available\u003c\/strong\u003e\u003cul\u003e\u003cli\u003eThere is no need to buy a new kit when reagents are exhausted.

The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. Thus, water hardness is actually a quantitative measure of these ions in the water. It is also now known that certain other ion species, such as iron, zinc, and manganese contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes.\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\u003eHI3812\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eTotal Hardness Chemical Test Kit - HI3812\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness, Total Measurement Type\u003c\/td\u003e\n\u003ctd\u003etitration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness, Total Range\u003c\/td\u003e\n\u003ctd\u003e0.0 to 30.0 mg\/L CaCO₃; 0 to 300 mg\/L CaCO₃\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness, Total Resolution\u003c\/td\u003e\n\u003ctd\u003e0.3 mg\/L (0.0 to 30.0 mg\/L range); 3 mg\/L (0 to 300 mg\/L range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness, Total Method\u003c\/td\u003e\n\u003ctd\u003eEDTA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness, Total Number 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\u003e460 g (1 lb.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e200x120x60 mm (7.9x4.7x2.4 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\u003cp\u003eHI3812 test kit comes with 30 mL hardness buffer, 10 mL calmagite indicator, 120 mL EDTA solution, 20 mL plastic beaker with cap, 50 mL plastic beaker with cap, and 1 mL syringe with tip.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI3812\" target=\"_blank\" rel=\"noopener\"\u003eTotal Hardness Chemical Test Kit - HI3812\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871256969585,"sku":"HI3812","price":3682.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3812_2.jpg?v=1792645976","url":"https:\/\/hannainst.in\/products\/total-hardness-chemical-test-kit-hi3812","provider":"hanna","version":"1.0","type":"link"}
