Product Overview

The SUP-TDS210-B Conductivity Controller is designed for continuous online monitoring of conductivity (EC), total dissolved solids (TDS), resistivity (ER), and solution temperature. It provides stable measurement performance for industrial water treatment applications while supporting automatic temperature compensation and isolated signal transmission.
Featuring a 2.8-inch LCD display, isolated 4–20 mA output, RS485 Modbus RTU communication, dual relay outputs, and flexible AC/DC power options, the controller can be integrated into a wide range of industrial automation systems. It is widely used in thermal power plants, water treatment systems, chemical processing, pharmaceutical manufacturing, food & beverage production, and municipal water applications.

Key Features

  • Measures conductivity (EC), TDS, resistivity (ER), and temperature simultaneously through one controller.
  • Provides isolated 4–20 mA output with excellent anti-interference performance for industrial environments.
  • Supports isolated RS485 communication for seamless integration with PLC, DCS, and SCADA systems.
  • Supports NTC10K and Pt1000 temperature sensors with automatic or manual temperature compensation.
  • Equipped with two configurable relay outputs for high/low alarm control and process automation.
  • Large 2.8-inch monochrome LCD display provides clear readings and simple operation in industrial environments.
