Industrial ORP Sensor
HydroMetric industrial ORP sensor is designed for continuous oxidation-reduction potential monitoring in municipal water, surface water, industrial process water and wastewater treatment. The combination-electrode design provides fast response and stable online measurement in fresh-water and seawater applications.

Applications
- Tap and municipal water ORP monitoring
- Surface-water monitoring
- Industrial process-water oxidation/reduction control
- Wastewater treatment process monitoring
- Fresh-water and seawater measurement
Installation & Integration
Install the probe where representative water flow reaches the sensing surface and where routine cleaning is possible. For PLC/SCADA integration, specify whether direct digital RS485 output or a separate transmitter/controller is required.
