AirSentry FTIR Open Path Multi-Gas Analyzer

The Cerex AirSentry FTIR multi-gas analyzer is the recognized choice in open path FTIR and the most reliable for monitoring industrial facilities, accidental releases, and hazardous waste site emissions. The system monitors from 5 to 1,000 meters and eliminates the need for many single point gas specific sensors, lengthy calibration, and laboratory analysis.

The Cerex AirSentry FTIR is the only commercial open-path FTIR evaluated in two USEPA SITE studies and proven capable of detecting, identifying, and quantifying air toxins. It is efficient as an alarm and easily integrated into your existing alarm system.
