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
