BC350 DPD Residual Chlorine / Total Chlorine Analyzer

The BC350 model DPD residual chlorine/total chlorine analyzer of Bebur is a water quality analysis device with a compact design, simple structure, and easy operation. This instrument uses the DPD colorimetric method to measure residual chlorine and total chlorine in water: Reagents are injected into the water sample through a reagent pump to complete the reaction, and then the DPD colorimetric method is used to accurately determine the concentration of the water sample. Users can achieve targeted measurement of residual chlorine or total chlorine by selecting different reagents. In addition, the instrument is equipped with a large-capacity data storage device, which can store over 10 years of test data, facilitating users to analyze the long-term water quality change trend of the water body.
