The ENDRESS+HAUSER Memosens CCS51D is a digital free chlorine sensor designed for accurate and stable measurement in drinking water, pool water, process water, and utilities in all industries. It offers a robust and low-maintenance solution for monitoring free chlorine levels, ensuring consistent disinfection even at low water volumes. With extremely fast response times, it enables efficient process control and provides precise measurement with long-term stability. The sensor can measure free chlorine concentrations ranging from 0 to 200 mg/l HOCl, making it suitable for a wide range of applications. Its amperometric measurement method and closed, membrane-covered measuring cell contribute to its reliability and low cost of ownership. The Memosens CCS51D can be easily connected to the Liquiline multiparameter transmitter for convenient combination with other relevant parameters of liquid analysis.
