Amperometric sensor for free chlorine

21st June 2019


Endress+Hauser has launched the Memosens CCS51D amperometric sensor for free chlorine measurement in process water, drinking water, water & wastewater treatment, cooling water, and all utilities and processes requiring clean, treated water.

Free chlorine is the most important disinfectant in water treatment due to its easy handling, the strong disinfecting effect and the residual effect. A precise dosing control can only be achieved by a fast and sensitive measurement. Memosens CCS51D features a special membrane design providing an extremely fast response time. It helps plant operators run their disinfection processes on tight limits and save on chemicals.

The sensor's convex membrane made of dense, dirt-repellent material prevents soiling and makes it extremely resistant to biofouling. Ultrasonic welding of the membrane to the sensor cap ensures its integrity, preventing dilution of the electrolyte and thus a drift of the measuring signal. This guarantees long-term stable measurements and gives water plant managers the security that the disinfection process is running smoothly, and the required disinfection results are achieved.

Memosens allows for direct commissioning of new sensors without further calibration. During on-going operation, plant operators can pre-calibrate sensors in the lab, swap them into the process with plug & play, and thus continue measuring faster. Finally, non-contact data transmission eliminates all measurement errors or even failures caused by humidity or corrosion.
