The instrument adopts the DPD method, the application of photoelectric colorimetric detection principle to replace the traditional visual colorimetric method. Eliminate the human error, thus greatly improve the measurement resolution. Measurement, when measured water sample in DPD tablets, water will become red. Then will the water sample in the photoelectric color seats, instrument will by comparing red depth so as to get residual chlorine concentration size. Can be applied to large, medium and small water and industrial and mining enterprises, swimming pool, life or industrial water of residual chlorine/total chlorine concentration detection, in order to control the water residual chlorine/total chlorine reaches the water quality standards.
