What do you use a chlorine sensor for?
Chlorine sensors are used to continuously monitor free chlorine, total chlorine or other chlorine compounds in water systems. In swimming pools and water treatment installations, they help optimise chemical dosing and maintain effective disinfection levels. In industrial applications, chlorine monitoring supports process control and compliance with water quality standards. Continuous measurements allow you to detect deviations immediately and automatically adjust dosing systems when necessary.
Features of chlorine sensors
Our chlorine sensors are designed for accurate and stable long-term measurements under demanding conditions. Many models feature membrane-covered or amperometric measurement technology to ensure reliable performance and minimal maintenance. Depending on the model, sensors are available with analogue or digital outputs for integration with controllers, dataloggers and monitoring systems. Their robust construction makes them suitable for continuous operation in water treatment systems and industrial environments.
Tips when buying a chlorine sensor
- Choose a chlorine sensor that matches the type of chlorine you want to measure, such as free chlorine or total chlorine.
- Pay attention to measurement range and response time.
- Consider sensor technology and maintenance requirements for your application.
- Check compatibility with your controller, datalogger or automation system.
- Evaluate calibration and cleaning requirements to ensure reliable long-term performance.
