Sabio - Model 6020 - SO2 Analyzer - Brochure

The Model 6020 SO2 Analyzer provides an accurate and convenient means of measuring low levels of Sulfur Dioxide in ambient air. The Model 6020 measures sulfur dioxide by detecting the fluorescence of SO2 when exposed to ultraviolet (UV) radiation at wavelengths near 214 nm. The SO2 molecule fluoresces (reradiates) at longer wavelengths of approximately 360 nm, which is detected and measured by a photomultiplier tube (PMT). Narrow band optical filters are used to separate the 215 nm excitation light from the 360 nm fluorescing light. The Model 6020 consists of a sample inlet, hydrocarbon scrubber (kicker), optics, UV lamp, reaction chamber, PMT, UV detector, and associated electronics.
