The HI3829F and HI3831F are simple colorimetric test kits that determine the concentration of free chlorine within a specified range: HI3829F - Free Chlorine Test Kit (0.0 to 2.0 mg / L) HI3829F - Free Chlorine Test Kit (0.0 to 2.5 mg / L) The importance of measuring free chlorine Disinfection is a killing process disease-causing organisms (or pathogens). Chlorine (Cl2) is a very effective 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 disinfecting swimming pools, spas and drinking water.In some areas where they use drinking water, they 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 odors, kill bacteria, and help remove unwanted elements. USEPA requires that residual disinfectant be present in final drinking water to ensure that disinfectant is available throughout the distribution system, and that chlorine acts as one of the disinfectants that provides that residue. 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. Key Features All necessary materials are included with the kit, such as the sample cup, color comparison cube, and dropper bottles. Both the 0.0 to 2.0 mg / L and 0.0 to 2.5 mg / L readings are determined to 0.5 mg / L resolution. It is not necessary to buy a new kit when the reagents are exhausted. The reagent set can be ordered to replace the reagents supplied with the kit. The HI3829F and HI3831F test kit are supplied with: - Color comparison cube - 20 ml of reagent 1 - 15 ml of reagent 2.
