ENVEA - Photoacoustic Infrared Spectroscopy (PAS) Analyzers
FromENVEA
CAI PAS Sense analyzers use photoacoustic infrared technology to measure many of the most commonly measured IR-absorbing gases. Gas selectivity is achieved through the use of optical filters that provide both a means of detecting the gas of interest and compensating for interfering gases and water. Both bench-top and rack-mounted PAS configurations are available.

An optional carousel is available to accommodate up to five additional gases. Typical applications for CAI PAS analyzers include:
- Vehicle exhaust measurements for Ammonia, Ethanol, Nitrous Oxide, CO2, CO and H2O
- SHED testing for Methanol, Ethanol, Toluene, CO2, R-134-A and H2O
- Process quality control
- Stack gases
- VOC/THC analysis
- Fermentation/greenhouse gases
- Trace gas analysis
- Occupational health and safety
- Livestock emissions
