Type: NOx Gas Bench for Engine Emission

Model No.:Gasboard-2201



Based on high-precision ultraviolet differential absorption spectroscopy gas analysis principle( UV-DOAS), our Gasboard-2201 NOx bench adopts flashing xenon lamp as light source. When the light is transmitted in the measured gas, the intensity of the differential absorption characteristic produced by each molecule in the gas in different bands is used to derive the gas concentration & type. Based on the special design and  a unique algorithm, the long path is returned to the gas chamber multiple times, the NOx bench detector can get strong absorption signal to support high sensitivity. With the advantages such as long service life and good stability, it can accurately measure the engine emission gas concentration of NO, NO2 and conforms the national standard GB 3847 and GB 18285 detection requirements.
