The Atmosphere Analyzer (AA) is a multi-gas analyzer for submarine use.

Product Overview

The AA comprises of 3 main gas sensing modules:

  • SIL2 O2 monitor, a functionally safe oxygen (O2) monitor
  • Mass spectrometer
  • FTIR spectrometer

It is capable of measuring up to 30 gases from up to 16 compartments via sample lines ensuring crew safety.

Life support gases which are monitored include oxygen (O2), carbon dioxide (CO2) and carbon monoxide (CO).
Fire gases which are monitored include hydrogen cyanide (HCN) and nitrogen oxide (NO).

Post analysis of data logs can identify new gas species in the submarine environment.

The AA also offers a large number of additional miscellaneous gases too, so it can be tailored to your specific requirements.
