SO₂ Analyzer

AMS-600 Ultraviolet Fluorescence SO2  Analyzer can detect SO2  with low concentration (ppb level) in ambient air. It is one of the gaseous analysis instruments of ambient air quality monitoring systems. Its core part is a non-pulse UV light source and photomultiplier tube. The principle is that the ultraviolet light source generates ultraviolet light, excites SO2  molecules in the gas chamber to generate fluorescence, and measures the fluorescence intensity through a photomultiplier tube. Since the fluorescence intensity has a linear relationship with SO2  concentration, the SO2  concentration is measured through the functional relationship between the light intensity signal detected by the photomultiplier tube and the intensity of the excitation light source.
