ProCeas( No sample pre-treatment No Heated Lines* Multi-Components Pre-Calibrated No interference No Drift Pr SO2 Trace analyzer Low level SO2 Detection in wet gas (stacks) O The ProCeas® SO2 Isa complete pre-callbrated laser Infrared spectrometer for measurement of louu level HCI ablent air.. xThe ProCeas® SO2 uses the patented OFCEAS (WO 03031949) IR Laser technology for enhanced specificity, selectivity, accuracy and stability (no instrumental response drift.) ' The ProCeas® SO2 uses a patented low-pressure sampling system (WO 2010058107) enabling low-cost installation thank to non-heated lines* and reduced maintenance. The ProCeas® SO2 is complete, reliable, robust, low-cost and easy-to-use solution for low level HCI analysis ambient air. ProCeas® Advantages & Benefits ' DIRECT MEASUREMENT No sample pre-treatment. OFCEAS technology associated with low pressure sampling enables direct measurement. The low pressure in the sampling system removes any risk for chemicals adsorption/desorption and condensation in the line. ' NO INTERFERENCE OFCEAS technology associated with low pressure sampling provides exceptional selectivity, enabling simultaneous multi-component measurement without interferences, regardless of the matrix. ' NO RE-ZERO; NO DRIFT The zero information is contained in the signal, enabling automated and intrinsic re-zero of the analyzer. C EASE-OF-USE The ProCeas® is pre-calibrated for your application. Initially packaged in a standard 19"rack, it includes a touch screen interface and on-board PC for local / remote control and realtime display/recording of results. ' EASE-OF-I The ProCeas® allows digital (Ethernet, RS485, RS232, ModBus), analog and TDR I/O’s. ' ROBUSTNESS The ProCeas® contains no optical moving parts and was designed and built strictly for industrial and on-board mobile applications. ' LOW MAINTENANCE High MTBF. In addition to containing no moving optical components, the IR sources (telecom type laser) are characterized by MTBF’s of 5 years. ' CLEAN LINES / FILTERS The low pressure sampling system enables low flow rates (3-9 L/h) without degrading response time. Accumulation of contaminants lines and filters is greatly reduced.
