Overview

The HM Digital PSC‑54 is engineered for water treatment professionals who require dependable and continuous measurement of EC and TDS. Its extended measurement range covers both low and high conductivity and dissolved solids levels, making it suitable for diverse water quality scenarios. The controller includes a clear LCD with temperature display and offers digital calibration for dependable accuracy. A 4‑20 mA output signal allows seamless connection to industrial PLCs, data loggers, and other monitoring equipment, while the built‑in relay can automatically control external devices like pumps or valves when measured values cross set thresholds. With a robust stainless‑steel electrode and complete set of included components, the PSC‑54 provides a reliable solution for automated water quality management.
