CL-201 Colorimetric Residual Chlorine Analyzer
Measurement principle:
Using DPD colorimetric method to detect the concentration of residual chlorine which is an measurement accurate, cost-effective and low maintenance instrument. It is suitable for the measurement of residual chlorine in chlorine disinfection process and monitoring of residual chlorine concentration in drinking water pipe network. Continuous operation 30 days of reagent dosage, realize unattended operation, operation and maintenance cost is low.
Features:
①The DPD standard colorimetric method
②The continuous operation of 30 days do not need to replace the reagent, simple operation, low operation and maintenance cost
③Two programmable relay, can set the concentration alarm
④It is suitable for measuring residual chlorine in tap water, circulating cooling water, sewage chlorination process of residual chlorine measurement and tap water pipe network.
