4-20MA Output Free Chlorine Sensor CL4.2 With Flow Cell For Drinking Water
Amperometric Membrane Method (Amperometric Membrane Method) residual chlorine sensor CL4.2 is a sensor technology commonly used to measure the concentration of residual chlorine in water. It is based on the principle of electrochemistry, by measuring the current to determine the content of residual chlorine in the water sample.
Advantage:
High sensitivity: The film-attached residual chlorine sensor has high sensitivity and can perform accurate measurement in the range of low residual chlorine concentration, which is very important for applications that require strict monitoring of water quality.
Real-time monitoring: This sensor can provide real-time residual chlorine concentration data, allowing users to quickly understand changes in water quality and take necessary measures to maintain water quality safety.
Quick response: The film-attached sensor has a fast response speed, and can quickly detect changes in residual chlorine, so that measures can be taken in time to protect water quality.
Stability: These sensors typically have good long-term stability and repeatability, providing accurate and reliable measurements over long periods of time.
Automation integration: The film-attached residual chlorine sensor can be equipped with RS485 and integrated with the automation system to realize automatic monitoring and alarm, thereby reducing the need for manual operation and intervention.
With its high sensitivity, real-time monitoring capability and stability, the film-attached residual chlorine sensor CL4.2 is mainly used in the design of drinking water environment.
