Versatile and proven Fourier Transform Infrared technology with up to 40 detection points.

The ACM 100 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 odours. Detection of new gases can be added at any time.

By choosing between two sample cells the  ACM 100 can detect either ppm levels for monitoring toxic gases or per cent 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 100 is easy to maintain. Since there are almost no consumable parts the cost of owning an ACM 100 is low.

An optional LonWorks® interface is ideal for connection to the Honeywell Analytics life safety system.

FT-IR analysis in four steps

1. An interferometer modulates a beam of  light  
    and sends it through a gas cell containing the
    air sample, where airborne chemicals in the
    sample absorb infrared light creating a
    spectrum unique to each chemical.

2. The absorbed light is measured at the 
    detector.

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

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