The CLD series chlorine dioxide sensors utilize amperometric technology for real time chlorine dioxide measurements. Applications include water treatment disinfection and chlorine dioxide generators. These sensors provide a fixed 4-20mA output which is temperature compensated. A power supply voltage of 12-24VDC is required. The CLD02 is designed for 0-2ppm measurements while the CLD10 features a measuring range of 0-10ppm. The newest addition to the line is CLD-01 for measuring 0-1ppm. A durable Teflon membrane is integrated into the cap for ease of replacement.  Electrolyte is also available and should be used to refill the membrane cap when replaced.  The sensor's body is constructed of Black PVC. A specialized acrylic flow cell (FC70) incorporates a vortex generator to prevent air bubbles from forming on the membrane surface which lead to erroneous readings.
