Serinus Gas Analyzer

The EC9850T SO2 trace analyzer is Ecotech's specially configured sulfur dioxide analyzer designed to measure low levels of SO2 with high accuracy.

The EC9850T SO₂ trace analyzer incorporates UV fluorescence spectrometry with microprocessor control for accurate and reliable measurement of sub-ambient levels of SO_2.

The EC9850T can measure levels of SO₂ to a sensitivity of 200ppt in the range of 0-2000 ppb. The SO₂ concentration is automatically corrected for gas temperature and pressure changes and can be displayed in units of ppb, ppm, μg/m³ or mg/m³.

Excitation (UV radiation) is measured by a reference detector and emission (fluorescence radiation) from the sample is measured by a photomultiplier tube (PMT) in a reduced atmosphere reaction cell.
