Industrial Water EC / TDS Conductivity Transmitter – 4–20 mA, 0–5 V, 0–10 V

Water Conductivity (EC) & TDS Transmitter is a compact, high-accuracy industrial sensor designed for continuous online monitoring of electrical conductivity and total dissolved solids in liquids.

It supports multiple industrial outputs (4–20 mA, 0–5 V, 0–10 V, and RS485 Modbus RTU), making it ideal for integration with PLCs, RTUs, SCADA systems, recorders, and industrial controllers.

With automatic temperature compensation, one-key online calibration, and electrode health detection, this transmitter delivers stable, reliable measurements in demanding process environments.
