Chlorine sensors continuously measure the concentration of chlorine in water and provide real-time insight into disinfection performance and water quality. In water treatment, swimming pools, cooling towers and industrial applications, maintaining the correct chlorine concentration is essential for effective disinfection and process safety. Unlike portable meters, chlorine sensors are permanently installed and provide continuous measurements for monitoring and automation systems. Looking to buy a chlorine sensor? Pay attention to measurement range, sensor technology, response time and compatibility with your controller or monitoring system. Read more
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.
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.
Are you unsure which chlorine sensor is most suitable for your application? We are happy to help you select the right solution based on practical experience.
Different chlorine sensors are available for drinking water, swimming pools, cooling water and industrial process applications. Selecting the right model depends on the type of chlorine being measured, the installation environment and the communication protocol used within your system.
