Description
The E+H Memosens CCS50E digital chlorine dioxide sensor is designed for monitoring chlorine dioxide concentrations in drinking water, process water, and industrial utility applications. It provides measurements across a wide range, from trace levels to 200 mg/L, helping operators maintain effective disinfection while minimizing chemical overdosing. The sensor can also be used to verify the absence of chlorine dioxide in applications such as beverage production and reverse osmosis systems.
The sensor features Memosens 2.0 technology, which supports reliable data transmission, simplified installation, and faster polarization times. Its rapid response and long-term measurement stability support continuous process monitoring and control. The sensor can be pre-calibrated and exchanged quickly using plug-and-play functionality, reducing downtime. It is compatible with Flowfit CYA27 and immersion assemblies and can be integrated with Liquiline multiparameter transmitters for combined liquid analysis measurements.
