COSAMS - not hydrogen sensitive
The COSAMS submarine gas sensor (carbon monoxide submarine atmosphere monitoring system) offers continuous real-time monitoring of carbon monoxide (CO) in the living accommodation and machinery spaces on submarines. As it is not sensititive to hydrogen (often used in fuel cells), like many carbon monoxide monitors are, the COSAMS will not produce 'false positives'.
Carbon monoxide can be generated on a submarine in several ways, from cooking and fire, to the incomplete combustion of diesel fuel and chlorate candles (which are used to generate oxygen).

Key features of the COSAMS
- Real-time continuous monitoring, with 90 days data-logging
- Uses an infrared rather than electrochemical cell - so it is not sensitive to hydrogen or water vapour
- Easy to maintain - can be maintained on the boat or in the dockyard, limiting downtime
- Built in auto-zero function to ensure stability
- Hardwearing - can withstand 22g shock and can withstand temperatures up to 50°c.
- Carbon monoxide (CO)
Where can it be used?
Two COSAMS units should be fitted in a submarine, one mounted to the fore, in the accommodation area, and the other aft, in the engine room. Each COSAMS indicates the local CO concentration on a colour LCD and transmits a corresponding 4-20mA signal to the submarine’s Central Air Monitoring System.
