pH & ORP Sensors (Endress+Hauser)
pH and ORP sensors are essential for water quality monitoring, chemical dosing, process control and environmental compliance. Endress+Hauser’s pH and ORP portfolio includes robust digital (Memosens) and analog sensors designed for reliable measurement in water, wastewater, mining, chemical, food and industrial processes.
What pH & ORP Sensors Are Designed For
These sensors measure:
- pH – acidity or alkalinity of liquids
- ORP (Oxidation-Reduction Potential) – disinfection strength, oxidation processes and chemical reactions
They are used in:
- Water and wastewater treatment
- Chemical dosing and neutralisation
- Mining and mineral processing
- Food and beverage production
- Industrial utilities and boiler feedwater
- Environmental monitoring
