The CCS51 free chlorine sensor is robust and low-maintenance. The sensor performs highly accurate measurement with high long-term stability in drinking water, pool water and process water; it can also reliably monitor the disinfection process even under low-flow conditions. The analog free chlorine sensor has a short response time, ensuring efficient process control and process safety. The CCS51 analog free chlorine sensor provides continuous measured values at the measuring point.
Benefits
Short response time (t90 < 25 seconds) with highly accurate display of the process status, enabling timely action in response to process changes and efficient process control.
Higher process safety: precise, long-term stable measurement enables permanent process monitoring and flexible adjustment of the disinfectant concentration as required.
The fluorescence sensor is low-maintenance and significantly reduces the operating costs of the measuring point compared with colorimetric measuring systems.
Used together with the Liquisys chlorine transmitter, it provides continuous analog free chlorine measured values at the measuring point.
Applications
The CCS51 free chlorine sensor meets the requirements of skid manufacturers and end users. It reliably measures:
Drinking water: ensuring reliable disinfection
Food: ensuring food safety with hygienic bagged and bottled packaging
Utilities: detecting the presence of free chlorine
Pool water: efficient disinfectant dosing
