Industrial RS485 Electrical Conductivity Sensor With TDS Salinity And Temperature Monitoring
The Industrial RS485 Water Electrical Conductivity Sensor is a high-precision water quality monitoring solution designed for continuous measurement of electrical conductivity in industrial, environmental, agricultural, and water treatment applications. Featuring an integrated probe and housing design, the sensor provides reliable conductivity measurements while simplifying installation and deployment. With an electrode constant of K=1, a measurement range of 1 to 2000μS/cm, a resolution of 0.1μS/cm, and an accuracy of ±1%FS, it delivers dependable real-time water quality data for professional monitoring systems.
Beyond conductivity measurement, the sensor incorporates intelligent conversion algorithms that simultaneously output salinity, TDS, and temperature values, providing comprehensive 4-in-1 water quality analysis. Automatic Temperature Compensation (ATC) ensures measurement accuracy across varying environmental conditions, while the RS485 ModBus-RTU communication interface enables seamless integration with PLCs, industrial controllers, IoT gateways, SCADA systems, Arduino platforms, and remote monitoring networks. Factory calibration and the included 1413μS/cm calibration solution allow immediate deployment and simplified maintenance.
