Powerful FTIR Technology for Monitoring Hazardous Gases

The ACM uses versatile and proven Fourier Transform Infrared technology to detect a wide range of volatile chemicals.  It uses the infrared fingerprint of each gas for identifications which are free of cross interferences.  It can also identify unknown chemicals or odors.  Detection of new gases can be added at any time.

By choosing between two sample cells the ACM can detect either ppm levels for monitoring toxic gases or percent levels for monitoring flammable gases.

The gas selections and alarm configuration for each point are easily configured or changed either from the front panel or remotely using just a web browser. Up to 15 gases can be detected at each point.  Up to 4 points can be sampled together for increased speed.  Because of its modular design and built-in diagnostics, the ACM is easy to maintain.  Since there are almost no consumable parts the cost of owning an ACM is low.

An optional LonWorks^® interface is ideal for connection to MST Technology's Life Safety System.

FTIR analysis in four easy steps

1. An interferometer modulates a beam of infrared light and sends it through a gas cell containing the air sample, where...

2.  Airborne chemicals in the sample absorb infrared light creating a spectrum unique to each chemical.  The absorbed light is measured at the detector, where...

3.  Infrared light intensity is digitized, then computed into an error-free infrared spectrum containing all of the analytical information, and...
