Cat Number: STEM-GLE-1652-LGH

Application: It adopts DPD photometric method and adopts photoelectric colorimetric detection principle to replace the traditional visual colorimetric method. Eliminate human error and have high measurement resolution. When the chloride ions in the water react with the DPD reagent during the measurement, the water sample will turn pink. Then put this water sample into the photoelectric colorimetric holder of the instrument, and the instrument will obtain the concentration value of the corresponding ion by comparing the depth of the color. It can be widely used in waterworks, industrial and mining enterprises, hospitals, domestic or industrial water inspection departments, etc., in order to control the ion concentration in the water to meet the specified water quality standards. This instrument complies with the national standard "GBT 5750.11-2009 Standard Test Method for Drinking Water" for the determination of disinfectant indicators.
