NO2 sensor Gasboard-2300

NDUVminiatureRS485

Introduction Gasboard-2300 NDUV NO2 gas bench adopts non-dispersive ultraviolet absorption (NDUV) technology and highly stable pulsed LED UV source to measure NO2 gas. It can measure the gas concentration of NO2 with high accuracy and strong anti-interference without NOx converter. Features • Direct detection for NO2 by NDUV with high accuracy • No necessary to use the complicated NOx converter • Suitable for ultra-low range monitoring, no moisture contamination • Modular design for easy integration Specifications Measurement: NO2 Range: NO2：0～1000ppm Accuracy: Abs. error＜ ±25ppm; Rel. error＜±4%;（Whichever is greater） Resolution: 1ppm Response time: T90≤4.5s Communication: RS-232 Power supply: 12V±0.2V，3.2A
