DPD Online Residual Chlorine/ Total Chlorine Water analyzer
The Bebur BC350Online Residual Chlorine/ Total Chlorine Water analyzer is acompact, well-structured and easy to operate water analysis instrument. The analyzer measures residual chlorine and total chloring in water using the DPD colorimetric method: Reagents are injected into the water sample by a reagent pump to complete the reaction,and the DPD Colorimetric method is then used to accurately determin the sample concentration. Users can select different reagents to achieve targeted measurement of residual chlorine or total chlorine. In addition, the instrument is equipped with a large-capacity data storage module,which can store test data for more than 10 years, helping users analyze long-term water quality variation trends.
