AquaSense-ORP

Long-life industrial ORP electrode with built-in temperature sensor, automatic compensation, and RS485 / Modbus output for continuous redox monitoring.

AquaSense-ORP measures the oxidation-reduction potential of natural and process waters with a long-life industrial in-line electrode. An integrated temperature sensor handles automatic temperature compensation, and the digital RS485 / Modbus RTU output makes it easy to integrate into existing telemetry and SCADA systems.

Overview

AquaSense-ORP is a digital oxidation-reduction potential (ORP) sensor designed for redox tracking in surface water, drinking water, wastewater, and industrial process flows. The platinum-tipped industrial electrode delivers strong long-term stability, while the integrated temperature element provides automatic temperature compensation across the operating range.

The sensor outputs RS485 with the Modbus RTU protocol, simplifying integration into telemetry, DAQ, and SCADA networks. It is a strong choice for disinfection control, environmental compliance, and any process where redox state needs to be tracked continuously.
