Application Scope
This analyzer can automatically detect residual chlorine concentration in water online. It adopts the reliable DPD colorimetric method (a national standard method), automatically adding reagents for colorimetric measurement. It is suitable for monitoring residual chlorine levels during chlorination disinfection processes and in drinking water distribution networks. This method is applicable for water with residual chlorine concentrations within the 0-5.0 mg/L (ppm) range.
