Overview

The HM Digital PSC‑50 TDS/EC Controller provides continuous monitoring and control of water conductivity and dissolved solids. It is engineered to maintain water quality by activating an alarm and switching relay contacts when TDS or EC levels rise above a preset limit. Once the levels drop back below the selected set point, the controller deactivates the alarm and returns the relay to its normal state. The unit includes an easy‑to‑read LED display with integrated temperature readout, digital calibration controls, and comes supplied with a sensor probe for plug‑and‑play operation. Its sturdy construction, clear interface, and flexible control options make it ideal for use in commercial and industrial water purification systems where maintaining precise water quality is essential.
