Overview

The HM Digital SM‑1EC in‑line EC monitor offers a straightforward and efficient solution for measuring the electrical conductivity of water flowing through a single line. With a user‑friendly digital readout, this compact device helps users quickly assess water quality as part of filtration or treatment systems without interrupting flow. The monitor is factory calibrated and includes a built‑in auto‑off feature that preserves battery life by powering down after a period of inactivity. Its easy installation and compatibility with standard fittings make it ideal for both residential and light industrial applications where ongoing water conductivity feedback is essential for performance and safety.
