The AA comprises of 3 main gas sensing modules:

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

It is capable of measuring up to 30 gases from up to 20 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.

  • Measures up to 30 gases continuously
  • Sample gas from 16 compartments (via sample lines)
  • A number of AA analyzers can be connected together to provide measurements from a greater number of compartments
  • Each measurement is datalogged so records can be maintained for the vessels life
