New Endress+Hauser Memosens CCS51D sensor for free chlorine provides high precision measured values, at low water volumes.

CCS51D features a special membrane design, helping plant operators run their disinfection processes on tight limits and with only as much chemical usage as is required.

This sensor’s convex membrane made of dense, dirt-repellent material prevents soiling and 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.

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