Product Overview

The SUP-TDS210-C Conductivity Controller is a microprocessor-based online analyzer designed for continuous measurement of conductivity (EC), total dissolved solids (TDS), resistivity (ER), and temperature. Compatible with multiple conductivity cell constants, it features automatic temperature compensation, dual alarm relays, isolated 4–20 mA output, and RS485 Modbus RTU communication. It is widely used in reverse osmosis systems, water treatment, industrial process control, food & beverage production, power plants, and laboratory applications.

Key Features

  • Supports conductivity (EC), total dissolved solids (TDS), resistivity (ER), and temperature measurement in a single controller.
  • Works with conductivity cells of K=0.01, 0.1, 1.0, and 10.0, covering applications from ultrapure water to high-conductivity industrial solutions.
  • Supports NTC10K and Pt1000 temperature sensors with both automatic and manual temperature compensation for improved measurement accuracy.
  • Equipped with isolated RS485 Modbus RTU communication and isolated 4–20 mA analog output for easy PLC, DCS, and SCADA integration.
  • Provides configurable high and low alarm relays for process monitoring and automatic control.
  • Simple front-panel operation with one-point calibration, electrode constant selection, and quick access shortcut keys.

FAQ

What can the SUP-TDS210-C measure?

The controller measures conductivity (EC), total dissolved solids (TDS), resistivity (ER), and temperature, depending on the selected operating mode.

Can alarm outputs be configured?

Yes. Two configurable relay outputs allow users to set high and low alarm thresholds for monitoring and process control.

Does the controller support different conductivity sensors?

Yes. It is compatible with conductivity electrodes having cell constants of K=0.01, 0.1, 1.0, and 10.0, making it suitable for a wide range of water quality applications.

Does the controller provide automatic temperature compensation?

Yes. It supports both automatic and manual temperature compensation using NTC10K or Pt1000 temperature sensors to improve measurement accuracy.
