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...
4. The computer examines the infrared spectrum, to
identify and to quantify each chemical present in the
air samples.
