Sensorex’s CLD500 Chlorine Dioxide Sensors use advanced amperometric measurement technology to provide highly accurate monitoring of chlorine dioxide in disinfection applications. With two models covering the 0-2 ppm and 0-10 ppm full scale ranges, CLD500 sensors can be used in new installations or as a field replacement for existing sensors in chlorine dioxide generators, pools and other water treatment systems. The CLD500’s advanced sensing membrane keeps cross sensitivity interference from free chlorine to a minimum.
