UV-DOAS Gas Bench

Gasboard-2205
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.
