The EC & TDS Sensor measures conductivity, salinity, and TDS with automatic temperature compensation. With IP68 protection, RS485 output, and low power use, its perfect for reliable water quality monitoring.

The EC & TDS Sensor with hook-up wires measures electrical conductivity (EC), salinity, and total dissolved solids (TDS) in liquids, making it ideal for monitoring water quality in a wide range of applications.

Built to industry standards, the sensor includes automatic temperature compensation (ATC) to ensure accurate readings regardless of temperature changes. The electrode is IP68-rated, while the transmitter is IP65-rated, offering waterproof protection for reliable, long-term use in professional environments.

The sensor supports MODBUS-RTU RS485 communication and 02V analogue voltage output, allowing easy integration with data loggers such as the SenseCAP S2100 – LoRaWAN Data Logger, converters, and display systems. Compact, energy-efficient, and cost-effective, this EC & TDS sensor provides a dependable solution for continuous, accurate water quality monitoring.
