portable residual chlorine / total chlorine analyzer

Product Details DGB-402A Portable Residual Chlorine/Total Chlorine Analyzer is designed and developed based on DPD colorimetric method. It can directly measure residual chlorine and total chlorine in water. It is easy to use, accurate and reliable. This method is the national standard for determining total chlorine in residual water in the field of water quality analysis. The method is widely used for the determination of residual chlorine and total chlorine in drinking water, landscape water, medical wastewater, swimming pool water, disinfectant and the like. Main feature  Adopt 515nm LED light source, long life and high precision;  High-performance low-power single-chip technology, good human-machine interface;  Support single-point and multi-point calibration, allowing users to edit calibration curves;  Supports two parameters for a total of 200 sets of test data, in line with the GLP specification;  Support battery power and support power management functions;  IP65 protection grade, good waterproof and dustproof performance.
