EWS-3ECV-FCl Free Chlorine Water Quality Sensor

Category Sensors for Drinking Water Tag Free Chlorine

Adopting the constant voltage measurement principle, the EWS-3ECV-FCl free chlorine water quality sensor can continuously and accurately detect Free Residual Chlorine content in water samples. It requires no reagent consumption and no replacement of the membrane cap or electrolyte.
Low power consumption design, Zero-point stability.
Connected to our TRM series transmitter and Ulik-Server Cloud Service to realize remote real-time monitoring and remote control.
