Serinus ® 51 SO 2 /H 2 S ANALYSER BENEFITS The Serinus ® range of analysers have been designed using our experience and knowledge gained from operating large air quality monitoring networks for more than 40 years. The result, instruments that integrate seamlessly into continuous monitoring networks. The Serinus ® 51 analyser delivers precise and reliable performance at excellent value. It combines pulsed fluorescence detection with an internal catalytic converter to sequentially measure H 2 S and SO 2 in the range of 0 - 2 / 0 - 20 ppm respectively with a detection limit of 0.3 ppb. The measurements involves two cycles. H 2 S is measured by passing the sample through an internal SO 2 scrubber which removes any SO 2 , the H 2 S is then converted to SO 2 using the internal converter and measured using the fluorescence technique. SO 2 is then sequentially measured by bypassing the SO 2 scrubber and converter and using the fluorescence technique to only measure the SO 2 concentration. APPROVALS • Based on the Serinus ® 50 SO 2 analyser with U.S. EPA and EN approvals • Russian approval: 56054-13. • Guaranteed performance with a two year warranty • Internal thermal catalytic H 2 S to SO 2 converter • User selectable measurement of SO 2 /H 2 S, H 2 S or SO 2 only • Minimise time spent on site performing maintenance through superior remote instrument control, diagnostic viewing and calibration • Comprehensive data logging and remote viewing of over 200 operational parameters • Versatile interfacing through RS232, USB, Bluetooth, analog and optional TCP/IP • Easier setup through an intuitive menu system with “Quick Menu”, advanced GUI and a large keypad with tactile keys • Instant display of operational status using illuminated traffic lights on the front panel • Removable flash memory stores 10 years of data, including up to 12 individual parameters and event logs.
