How does amperometric titration technology compare to CL17sc measurements for chlorine?
Summary
amperometric titration and CL17sc
Answer

Amperometric titration has USEPA approved methods for chlorine measurement which usually has good correlation with the DPD colorimetric method used with the CL17sc. One needs to ensure the CL17sc is in good operating condition and on the default calibration setting. The grab sample must be representative for both types of analysis and the comparative analysis must be conducted as soon as possible after obtaining the sample.
