　　Online residual (total) chlorine analyzer

Product model: SS-CL17A

Application environment:

Suitable for measuring residual (total) chlorine in chlorine disinfection processes such as drinking water, wastewater, and industrial circulating cooling water, as well as monitoring residual (total) chlorine in drinking water pipe networks.

Testing method:

DPD colorimetric method: The residual chlorine/total chlorine online analyzer establishes a zero reference point by measuring the blank absorbance, and compensates for the color and turbidity of the sample before measuring chlorine. Afterwards, the indicator solution and buffer solution are added to the sample, and the sample undergoes a color reaction using a magnetic stirrer. Subsequently, the colorimeter measures the absorbance of the transmitted sample, compares the obtained absorbance with the reference standard, and obtains the measurement result.
