Description

MGL Series – UV DOAS is a flue online monitoring gas analyzer. This analyzer is based on UV DOAS principle. It can measure SO2, NO, NO2, O2,
NH3, CO, CO2, Cl2, O3, H2S, HCl, CH2I. With high accuracy and reliability, low operating costs, fast response time, wide measurement range and application fields. This principle platform consists of light sources, gas chamber, optical and spectroscopic and other components. Ultraviolet light is sent by the light source through the optical window into gas chamber and absorbed by the sample gas through the gas chamber. The light carrying sample absorption information gathers through lens coupled into fiber and then transmits through the optical fiber into spectrometer. After the light splitting and photo-voltaic conversion, absorption spectrum is obtained and analyzed to calculate the concentration of the related components in gas.
