SPS-CI-C Free Chlorine Water Quality Sensor
Based on the principle of constant voltage method measurement, the free chlorine water quality sensor can continuously and accurately determine the free chlorine or chlorine dioxide of water samples without consuming any reagent or replacing the diaphragm and electrolyte. Measuring range: 0-2mg/L, 0-5mg/L, 0-20 mg/L. DC12 V-DC24 V power supply, RS485 Modbus RTU communication.
The free chlorine sensor is widely used in water supply, secondary water supply, municipal networks, disinfection processes, and other fields to provide customers with reliable monitoring data.
Parameter: Free Chlorine, Temperature
- . No need for any reagents
- . No need to change diaphragms and electrolyte
- . Easy to install
- . Low maintenance cost
- . Zero-point stability
