These reagents follow the Calmagite method in which the reaction between calcium and the reagent causes a violet tint in the sample. When the HI720-25 reagents are added to the sample,  the reaction will take place and the HI720 will determine the concentration from the color that is produced. The results will be displayed in ppm of calcium hardness as CaCO\u003csub\u003e3\u003c\/sub\u003e. These reagents are designed to be used with samples that have an expected range of 0.00 to 2.70 ppm CaCO\u003csub\u003e3\u003c\/sub\u003e.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI720-25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Calcium Hardness Checker\u003csup\u003e®\u003c\/sup\u003e HC Reagents (25 Tests) - HI720-25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e Packets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003e adaptation of the Standard Methods for the Examination of Water and Wastewater, 18\u003csup\u003eth\u003c\/sup\u003e edition, Calmagite method.
