Redox Potential Sensor

Redox Potential Sensor

Product overview

The redox sensor uses a platinum electrode as the indicator electrode, and an Ag/AgCl reference electrode forms a galvanic cell with the water sample. The redox potential of the platinum electrode relative to the saturated Ag/AgCl reference electrode is measured with an electronic millivoltmeter, then converted to the redox potential relative to the standard hydrogen electrode as the reported result.

Where:

• E n — Redox potential of the tested water sample (mV)
• E ind — Measured redox potential of the water sample (mV)
• E ref — Potential of the saturated Ag/AgCl electrode at the measurement temperature (mV)

Key features

• Industrial-grade composite electrode, suitable for harsh working environments
• Built-in NTC temperature sensor with accuracy up to ±0.1°C
• Corrosion-resistant housing with IP68 waterproof rating for long-term underwater operation
• RS485 communication interface with standard Modbus protocol for easy integration

Applications

• Surface water
• Municipal sewage
• Industrial wastewater
• Industrial process water
• Swimming pools
