Endress+Hauser’s new Memosens CCS50D chlorine dioxide sensor supports safe and effective disinfection for clean drinking water, 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 prevents dilution of the electrolyte, providing long-term stable measurements and security in the disinfection process. Direct commissioning of new sensors can be done without further calibration, and contactless data transmission eliminates measurement errors or failures caused by humidity or corrosion. 888-363-7377; www.us.endress.com
