Model 450i Hydrogen Sulfide — Sulfur Dioxide Analyzer Datasheet

Utilizing pulsed fluorescence technology, the Model 450i H2S and SO2 analyzer operates on the principle that H2S can be converted to SO2. As the SO2 molecules absorb ultraviolet (UV) light and become excited at one wavelength, the molecules then decay to a lower energy state, emitting UV light at a different wavelength.
