RS485 Industrial Water Electrical Conductivity (EC) Sensor (K=1, Multi-Parameter & Pre-Calibrated)

This product is an industrial-grade water electrical conductivity sensor. The probe and housing are integrated into a single unit, resulting in a simple and convenient design for accurate measurement of water electrical conductivity. It features an electrode constant K=1, a measurement range of 1~2000 μS/cm, a resolution of 0.1 μS/cm, and an accuracy of ±1%FS. It also includes salinity and TDS conversion functions, allowing for the output of salinity and TDS data, meeting the needs of multi-parameter water quality monitoring.

The electrical conductivity sensor is equipped with an RS485 communication interface and supports the standard ModBus-RTU protocol. Tutorials are provided for connecting the sensor to Arduino development boards and DFRobot LoRaWAN, enabling quick setup of a test environment and real-time data monitoring. A built-in temperature sensor provides automatic temperature compensation, ensuring accurate and reliable data output under varying environmental conditions.

The electrical conductivity sensor is rigorously calibrated before leaving the factory and is ready for immediate use without further calibration. It also comes with a conductivity calibration solution, allowing users to quickly optimize measurement accuracy after prolonged use through register settings. With an overall waterproof rating of IP68, it can be submerged in water for extended periods, making it suitable for aquaculture, tap water monitoring, drinking water treatment, hydroponics, and agricultural irrigation applications.
