JW-DDM-206(K05)conductivity sensor is designed for online conductivity and TDS monitoring in drinking water, surface water, industrial water treatment, agricultural irrigation, and environmental water quality systems. It supports RS485 Modbus RTU output and IP68 immersion installation for long-term monitoring.
2. Product Overview
JW-DDM-206(K05)conductivity sensor is an online EC and TDS monitoring probe for continuous water quality measurement. It is suitable for drinking water, surface water, industrial water treatment, agricultural irrigation, and environmental monitoring projects.
With RS485 Modbus RTU communication, the sensor can be connected to PLC, DCS, industrial control computers, universal controllers, paperless recorders, touch screens, RTUs, and IoT gateways. The IP68-rated housing and 3/4 NPT thread allow reliable immersion installation or installation in pipelines and tanks.
The sensor supports multiple conductivity ranges, including 0–20 μS/cm, 0–200 μS/cm, 0–20000 μS/cm, and 0–200 mS/cm, making it suitable for low-conductivity water and high-conductivity industrial applications. Automatic Pt1000 temperature compensation helps maintain stable measurement performance in changing water conditions.
