Combustion control
ESP filter protection
Vent headers
Vapor recovery
Features and Benefits
Tunable Diode Laser spectroscopy
Dependable, industry-proven technology
Simple installation
Thanks to probe design and single flange connection
In situ measurement
Direct measurements in the gas stream are fast and reliable
SpectraID technology
For highly reliable O2 measurement
Low cost of ownership
No sampling or conditioning equipment. Annual verification and periodic optics cleaning are the only maintenance
Low nitrogen purging consumption
For lower operation costs
Predictive ISM diagnostics
Continually monitor optical path quality to determine when cleaning will be required
