The HI3831F is a colorimetric chemical test kit that determines the concentration of free chlorine within a range of 0.0 to 2.5 mg/L (ppm). The HI3831F is supplied with all the reagents and equipment necessary to perform the analysis. The test kit contains enough reagents to perform approximately 50 tests.
All necessary materials are included with the test kit, such as the color comparison bucket and reagent dropper bottles.
High resolution
Readings of 0.0 to 2.5 mg/L are determined at a resolution of 0.5 mg/L.
Replacement reagents available
Importance of use
Disinfection is a process of killing organisms (or pathogens) that cause disease. Chlorine (Cl2) is a highly 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 effective form of chlorine for the disinfection of swimming pools, spas and drinking water.
Drinking water municipalities add elemental chlorine to the water supply in the form of chlorine gas, liquid sodium hypochlorite or dry calcium hypochlorite. In water, these form free chlorine ions, which destroy disease-causing pathogens, reduce odor, kill bacteria, and help eliminate unwanted items. The USEPA requires that residual disinfectant be present in the finished drinking water to ensure that disinfectant is available throughout the distribution system, and that chlorine acts as one of the disinfectants that provides such residual. However, the EPA has also set a maximum contaminant level of 4.0 mg/L for free chlorine due to potential health effects above this level.
