What do you use a pH sensor for?
pH sensors are used to continuously monitor the acidity of irrigation water, nutrient solutions and process water. In horticulture, they help optimise nutrient uptake and maintain stable growing conditions. In water treatment and industrial applications, pH measurements support dosing systems and automated process control. Continuous monitoring allows you to detect deviations immediately and respond before they affect your process.
Features of pH sensors
Our pH sensors are designed for accurate and stable long-term measurements. Many models feature high-quality reference systems and robust sensor materials that ensure reliable performance under demanding conditions. Depending on the model, sensors are available with analogue or digital outputs for easy integration with controllers, dataloggers and monitoring platforms. Their industrial design makes them suitable for continuous use in greenhouses, water treatment plants and industrial installations.
Tips when buying a pH sensor
- Choose a pH sensor that matches your application and installation environment.
- Pay attention to measurement accuracy and long-term stability.
- Consider sensor materials and reference systems for aggressive or contaminated media.
- Check compatibility with your controller, datalogger or automation system.
- Evaluate maintenance and calibration requirements to ensure reliable long-term performance.
