EC/TDS Controllers

EC/TDS controllers are online instruments that continuously monitor and control conductivity or total dissolved solids in water and process lines. A reliable EC/TDS controller in Pakistan is essential for RO plants, softeners, boilers, cooling towers, DM plants, pharma purified water, beverage lines and wastewater treatment, where water quality directly affects scaling, corrosion, product quality and compliance.

These online conductivity/TDS controllers work with industrial conductivity cells installed in pipelines, tanks or sample lines. They display real-time EC/TDS values and provide 4–20 mA outputs, relay contacts and often Modbus/RS485 communication for PLC, SCADA and BMS integration. Programmable setpoints and hysteresis allow automatic control of dosing pumps, blowdown valves and makeup water, keeping TDS and conductivity within the required range for RO feed, boiler drum, cooling tower circulation or process water loops. Features such as temperature compensation, multi-point calibration, alarms, data logging and password protection help operators maintain stable operation with minimum manual intervention.
