High measurement accuracy
The minimum detection limit of SO2 , NO2, NO can be 1mg/m3 (15m optical path) Ultraviolet has no moisture absorption, undisturbed by moisture and dust. No cross interference between the gas being measured (see table 1) NO and NO2 can be measured at the same time, dispense with converter High reliability
White cell + DOAS + PLS technology, small amount of zero drift and span drift Modular design No optical moving parts and no vibration influence Strong gas cell, low cost Spectrum automatic adjustment technology, long free maintenance cycle Light source adopts the pulse source, the service life is 10 years
