The SENSOREX CLD410 is a chlorine dioxide gas sensor for continuous air monitoring. It uses a 3-electrode electrochemical cell to provide an analog output proportional to chlorine dioxide levels. The sensor measures 0-1 ppm with 0.01 ppm resolution, requires a 5-12 VDC power supply, and outputs 4-20 mA. It has ±3% accuracy and includes an internal temperature sensor for compensation. Designed for fixed installation, it features an ABS plastic housing and a response time of <60 seconds.
