EC9850T TRACE SULFUR DIOXIDE ANALYSER The Ecotech Model EC9850T Trace Sulfur Dioxide (SO2) analyser incorporates UV pulsed fluorescence spectrometry with microprocessor control for accurate and reliable measurement of sub-ambient levels of SO2. The EC9850T can measure levels of SO2 to a sensitivity of 200 ppt 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). APPROVALS • EC9850T is U.S. EPA approved (Automated Equivalent Method EQSA-0193-092). FEATURES • Specially selected high output UV lamp operating at 214 nm. • Extremely low sensitivity to NO interferences. • Scrubbed sample air is used for background zero to minimise discrepancies between air quality of the sample and background air. • Auto-zero routine allows the analyser to periodically check and correct for cell contamination. • Kalman digital filter continuously provides the best compromise between response time and noise reduction. • Internal data logging uses Flash ROM to store up to 175 days of 5 minute averaged data.
