SO2 Stack Gas Monitor

SO2 Monitor uses fluorescence technique and is a very sensitive and specific method for detection of SO2. The optical excitation of SO2 molecules results in fluorescence in the wavelength region typically between 240-420 nm and the fluorescence intensity is related to SO2 concentration. The dependence of fluorescence intensity on moisture content,
hydrocarbons, etc. are avoided by using suitable techniques which makes the analysis independent of these parameters.
