Product Overview The residual chlorine tester is suitable for the detection of residual chlorine concentration in large, medium and small water plants and industrial and mining enterprises, domestic or industrial water, in order to control the residual chlorine of water to meet the specified water quality standards. The instrument uses tetramethylbenzidine or its neighbors. The tolidine method replaces the traditional visual colorimetric method with the principle of microcomputer photoelectron colorimetric detection. The human error is eliminated, so the measurement resolution is greatly improved. When measuring, when the water sample is poured into the reagent, the water sample will turn yellow. The water sample is then placed in the photoelectric color holder, and the meter will obtain the concentration of residual chlorine by comparing the yellow shades.
