NO2 sensor Gasboard-2200

NOnitrogen oxideUV-DOAS

Introduction Gasboard-2200 UV-DOAS NOx gas bench adopts high-precision ultraviolet differential absorption spectroscopy gas analysis technology to measure NO & NO2 simultaneously. It’s widely used by gas analyzers and PEMS manufacturers due to its flexible integration, high quality and easy maintenance. Features • Direct detection for NO, NO2 simultaneously without NOx converter • No cross-interference between measurement gases • Modular design for easy integration • Longer lifetime, no regular replacement Specifications Measurements: NO&NO2 Range: NO: 0-5000ppm, NO2:1000ppm (Measure range can be customized) Resolution: 1ppm Precision: Abs error: ＜25ppm; rel. error:＜4% （Whichever is greater） Response time:＜4.5s Warm-up: 30min Output: RS-232 or RS-485 Operation temperature (Indoor): 5～40℃ Operation Voltage: ±12V, 5V Operation Power: ＜70W Relative Humidity: ≤ 85% Dimensions: 250*150*155 mm (Length*Width*High)
