Features

Support for long-line calibration

In large factories or outdoors, the distance is often considerable. Long-line calibration technology automatically compensates for signal attenuation and impedance deviation.
Supports multiple installation methods

Supports panel, wall, or pipe mounting for flexible installation, helping you minimize selection errors and avoid additional procurement costs.
Historical Data

Helps you meet environmental audits. With one-click data query, you can quickly analyze water quality trends, optimize processes, and trace abnormal fluctuations to reduce downtime risk.
