NO2 sensor Gasboard-2205

SO2NOUV-DOAS

Introduction Gasboard-2205 series UV-DOAS gas bench adopt high-precision ultraviolet differential absorption spectroscopy gas analysis technology. With flashing xenon lamp as light source, when the light is transmitted in the measured gas, the intensity of the differential absorption characteristic produced is different which is used to derive the gas concentration & gas type Using a unique algorithm, the long path is returned to the gas chamber multiple times to get high sensitivity & strong absorption signal, at the same time it support long service life and good stability. It can accurately measure the gas concentration of SO2, NO and NO2. The measurement range is less than 100mg/m3, which can completely fulfill the needs of the ultra-low emission monitoring market. Features Advanced UV DOAS sensor for Measurement of ultra-low SO2, NO ≤250ppm, the loweat range to be 0-50mg/m3 & Optional NO2 One chamber for up to 3 gases components measurement simultaneously Measurement NO2 directly without converter, and lowest to 100mg/m3 Automatic temperature compensation No moisture & vibration interference High precision, good stability and long life Specifications Gas Type:SO2,NO,NO2,SO2+NO, SO2+NO+NO2 Technology: UV-DOAS Applications: Ultra-low emission flue gas detection Motor vehicle exhaust emission test Chemical plant gas concentration measurement Combustion boiler emission gas measurement Industrial waste water treatment gas monitoring Biogas project purification, monitoring before and after desulfurization Industrial process gas monitoring Gas Analyzer / System Integration Other Characteristics:RS 232; 4‐20mA (Optional); ±2%FS accuracy; 0.1ppm resolution;
