EWS-3EMC-FCl Free Chlorine Water Quality Sensor

Category Sensors for Drinking Water Tag Free Chlorine

The sensor adopts membrane-covered amperometric potential static 3-electrode, which effectively improves the measurement stability and accuracy of the sensor.
The measurement of residual chlorine by the sensor is not disturbed by the pH environment and does not require a separate pH compensation function.
The sensor can be equipped with our TRM series transmitter and Ulik-Server Cloud Service to realize remote real-time monitoring, as well as remote operation and maintenance of equipment.
