YZ-1Z Residual chlorine dioxide dual-use instrumentDetailed product description：

1、 Product Overview
The YZ-1Z residual chlorine dioxide dual-use instrument is suitable for detecting the concentration of residual oxygen and chlorine dioxide in large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water, in order to control the residual chlorine and chlorine dioxide in water to meet the specified water quality standards.

2、 Principle:
The YZ-1Z residual chlorine dioxide dual-use instrument uses the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved. When measuring, the water sample will change color when the reagent is poured into it. Then place the water sample into the photoelectric colorimetric stand, and the instrument will compare the color depth to obtain the concentration of the water sample.
