Outline	This is a simple measurement kit using tablets, but it can still obtain measured data similar to the Test Methods for Drinking Water. Kit Contents: DPD Tablet (Mixture tablet of 0.002 g of DPD and 0.048 g of Sodium Sulfate, Anhydrous) ... 1 bottle x 100 tables KI Tablet (0.05 g of Potassium Iodide/tablet) ... 1 bottle x 100 tablet Phosphate Buffer Solution (pH 6.5) ... 1 bottle x 8 mL Color Tone Table ... 1 sheet Features: Easy operation (1) No weighing is required for DPD (N, N-Diethyl-p-phenylenediamine Sulfate), KI (potassium iodide) because they are supplied in tablets.(2) For the buffer solution, the concentrated liquid is supplied in a convenient dropper bottle.(3) Measurement can be made by comparing the developed color with the color tone table. Measurements are possible with one test tube. (1) Both free residual chlorine and combined residual chlorine can be measured in one test tube. Chlorine is used for sterilization and disinfection of drinking water and swimming pool water. Chlorine displays disinfecting action in the form of hydrochlorous acid in water, but reacts with suspended matters, organic matters, metallic salts, etc. in water or dissipates in the atmosphere, and its concentration lowers and disinfecting action is lost. Therefore, residual chlorine in water is measured from the viewpoint of health management.Presently, the orthotolidine method is a mainstream of residual chlorine measurement, but carcinogenicity of orthotolidine has been pointed out and the DPD method has been attracting attention of the people concerned.The DPD method measures residual chlorine by comparing the standard colorimetric liquid to pink to pinkish red color developed by allowing residual chlorine to react with diethyl-p-phenylenediamine (DPD).The present product is a simplified residual chlorine analysis kit with this DPD method adopted as the working principle.
