Conductivity Sensor – TDS – Salinity

Description

The Conductivity and TDS Sensor is designed for continuous, high-precision monitoring of electrical conductivity and total dissolved solids in water. Utilizing a reliable four-electrode design, it ensures accurate measurements across a wide range of concentrations. The sensor features built-in temperature compensation, digital RS-485 output, and supports MODBUS protocol, making it ideal for integration into automated monitoring systems.

Key Features:

• Dual parameter measurement: conductivity and total dissolved solids (TDS)

• RS-485 digital output with MODBUS protocol for seamless system integration

• Four-electrode technology for stable, wide-range performance

• Automatic temperature compensation for accurate readings in fluctuating environments
