HI3831F Free Chlorine Test Kit With Color Cube The HI3831F is a colorimetric chemical test kit that determines the free chlorine concentration within a 0.0 to 2.5 mg/L (ppm) range. The HI3831F 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. • Complete setup · All required materials are included with the test kit, such as the sample beaker, color comparison cube, and reagent packets and dropper bottles. • High resolution · Readings from 0.0 to 2.5 mg/L are determined to 0.5 mg/L resolution. • Replacement reagents available · There is no need to buy a new kit when reagents are exhausted. The HI3831F-050 can be ordered to replace the reagents supplied with the kit. Signicance of Use Disinfection is a process of killing disease-causing organisms (or pathogens). Chlorine (Cl«) is a very desirable disinfectant because, when mixed with pure water, it reacts to form hypochlorous acid (HOCl) and hydrochloric acid (HCl). HOCl (free active chlorine) is the most eective form of chlorine for disinfection of pools, spas, and drinking water. Drinking water municipalities add elemental chlorine to the water supply as chlorine gas, liquid sodium hypochlorite, or dry calcium hypochlorite. In water these form free chlorine ions, which destroy disease-causing pathogens, reduce odor, eliminate bacteria and help to remove unwanted elements. The USEPA requires that residual disinfectant is present in nished drinking water to ensure there is disinfectant available throughout the distribution system, with chlorine acting as one of the disinfectants that provides said residual. However, the EPA has also set a maximum contaminant level of 4.0 mg/L for free chlorine due to potential health eects above this level.
