Features

4-electrode Technology for Wide Measuring Range

Adopts 4-electrode principle to reduce polarization effect, wide measuring range up to 200mS/cm, suitable for high salinity water. It measures conductivity, salinity, TDS and temperature simultaneously, with built-in temperature sensor for automatic compensation to ensure stable and accurate readings.
Corrosion Resistant PPS Housing

PPS engineering plastic housing, excellent chemical resistance and anti-aging performance for long-term online monitoring in saline and corrosive water. Separate M16 connector cable with customizable length.
Standard Structure & Digital Communication

1" NPT thread on both ends for easy installation. The online digital conductivity & salinity sensor has RS485 Modbus communication with strong anti-interference, easy integration with PLC and industrial control systems.

Application

Designed for seawater, brine and high-salinity wastewater. The online digital conductivity & salinity sensor is widely used in marine water monitoring, mariculture, salt chemical industry, seawater desalination and high-salinity wastewater discharge monitoring.
