WQS-RC series Residual Chlorine sensor manual

Product description

This product is a device for measuring the concentration of residual chlorine (hypochlorous acid and hypochlorite ion concentrations) in water bodies. Adopting a three-electrode system, it features high measurement accuracy, long service life, and no need for frequent calibration. It is suitable for automatic chemical dosing control in circulating water, chlorine dosing control in swimming pools, as well as the accurate measurement of residual chlorine content in aqueous solutions in drinking water treatment plants, drinking water distribution networks, swimming pools, and hospital wastewater.

Features

  • The residual chlorine measurement range is 0-2mg/L, 0-8mg/L, 0-20mg/L, with a resolution of 0.01mg/L.

  • Integrated design with direct 485 signal output, eliminating signal interference

  • 3/4-inch top and bottom mounting thread design for easy installation.

  • Protection class IP68.

  • Adopts advanced membrane-free constant voltage sensor, no need to replace membranes and reagents.

  • RS485 communication interface: MODBUS RTU communication protocol allows easy connection to computers for monitoring and communication.

  • Modbus communication address can be set, and the baud rate can be modified.

  • The device adopts wide voltage power supply, suitable for DC 7~30V.
