The Memosens CCS50D chlorine dioxide sensor supports safe and effective disinfection for pathogen-free cooling water and high-quality process water. The sensor features a convex membrane made of dense, dirt-repellent material that prevents soiling and makes it resistant to biofouling. Ultrasonic welding of the membrane to the sensor cap ensures its integrity, preventing dilution of the electrolyte and guaranteeing long-term stable measurements. The product line allows for direct commissioning of new sensors without further calibration. During ongoing operation, plant operators can precalibrate sensors in the lab and swap them into the process with plug and play.
