Dragino DR-EC200 Four-Electrode Conductivity Probe for Dragino WQS

The Dragino DR-EC200 is a four-electrode conductivity sensor designed for use with the Dragino WQS water quality system, reliably measuring high conductivity ranges such as seawater. It operates on 7–30 V DC, has very low power consumption of < 0.5 W, and communicates via an RS485 interface (9600 baud). Its electrical conductivity measurement range extends from 1 to 200,000 µS/cm with 1 µS/cm resolution and ±1% FS accuracy, supplemented by salinity measurement from 0–70 PSU and temperature measurement from −5 °C to +80 °C. The sensor offers automatic temperature compensation, is built with IP68 protection and a pressure resistance of 0.6 MPa for harsh outdoor and underwater applications, and is ideal for continuous monitoring in seawater, aquaculture, wastewater, environmental, and drinking water applications when used in conjunction with the Dragino WQS gateway and IoT systems.
