CL17/CL17D residual (total) chlorine detector

-Product Overview:
The Hash CL17/CL17D residual (total) chlorine detector uses the DPD colorimetric method to detect residual chlorine. With a built-in calibration curve, it automatically samples and analyzes every 2.5 minutes, compensates for turbidity and chromaticity, and diagnoses automatically. It is an online residual chlorine analyzer that can operate without human monitoring.

-Working principle:
The CL17/CL17D residual chlorine detection/determination instrument uses DPD (N, N-diethyl-1,4-phenylenediamine) colorimetric method to detect the concentration of chlorine. Due to the addition of buffer reagents, the sample is adjusted to a certain pH range, and DPD reacts with residual chlorine or total chlorine in the water sample to generate a purple red compound. The residual chlorine detector uses spectrophotometry to measure its absorbance changes and obtain the concentration of residual chlorine/total chlorine in the water sample.

-Application industry:
CL17 residual (total) chlorine detection/determination instrument - conventional version can measure residual chlorine, pH value, temperature, suitable for measuring residual (total) chlorine in chlorine disinfection processes such as drinking water, wastewater, and industrial circulating cooling water; The CL17D residual (total) chlorine detection/determination instrument - pipe network version is suitable for monitoring the concentration of residual (total) chlorine in drinking water pipe networks.

-Instrument features:
The residual chlorine detection/determination instrument adopts DPD colorimetric method, which can detect residual chlorine or total chlorine.
The residual chlorine detection/determination instrument utilizes built-in curve calibration for more accurate measurement.
It has automatic turbidity, chromaticity compensation, and automatic diagnostic functions to reduce measurement errors.
The residual chlorine tester realizes automated operation analysis, with an analysis cycle of about 2.5 minutes (conventional version)/10 minutes (pipeline version).
A set of reagents can automatically run the residual chlorine tester for 30 days, with simple operation and maintenance, and can be used for unmanned monitoring stations.
The residual chlorine tester can be connected to an automatic chlorine pump to achieve automatic chlorine addition.
