F O RMAL DEHYDE analyzer Pr o C e a s No sample pre-treatment No Heated Lines* Multi-Components Pre-Calibrated No interference No Drift Low l e ve l F o r m a lde hy de D e te c tio n i n a mb i e n t a ir The ProCeas Formaldehyde is a complete pre-calibrated laser infrared spectrometer for measurement of Formaldehyde in ambient air. The ProCeas Formaldehyde uses the patented OFCEAS (WO 03031949) IR Laser technology for enhanced specificity, selectivity, accuracy and stability (no instrumental response drift.) The ProCeas Formaldehyde uses a patented low-pressure sampling system (WO 2010058107) enabling low-cost installation thank to non-heated lines* and reduced maintenance. The ProCeas Formaldehyde is a complete, reliable, robust, low-cost and easy-to-use solution for the Formaldehyde analysis in ambient air. Ad va n t a ge s & B e ne f its 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. 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 real time display / recording of results. EASE-OF-INTEGRATION 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.
