Advanced ORP Sensors for Precise Oxidation-Reduction Monitoring

Industrial-grade ORP sensors built to monitor water disinfection and redox reactions across demanding water systems

Role of ORP Sensors in Enhancing Water System Performance

Oxidation-Reduction Potential (ORP) sensors are essential for monitoring the electron exchange capabilities in water, which reflects the system’s capacity to oxidize or reduce substances. These readings are critical in applications involving disinfection, corrosion control, and chemical dosing, where even slight changes in redox balance can impact safety and efficiency.ORP sensors offer rapid, real-time feedback and are widely used in municipal water treatment, aquaculture, industrial processing, and environmental monitoring. Their ability to detect contaminants, monitor disinfection levels, and support automated chemical control makes them indispensable in modern water systems.Water Quality Instruments provides a full range of ORP solutions tailored to meet the needs of B2B clients across North America.
