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.
EASE-OF-USE
Our gas analyzers are pre-calibrated for your application. Iniially 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
Our gas analyzers allow digital (Ethernet, RS485, RS232, ModBus), analog and TDR I/O’s.
ROBUSTNESS
Our gas analyzers contain no optical moving parts and were 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.
SAFE
ATEX compliant configuration available.
