Designed specially with diesel-powered military submarines in mind, this compact, robust O2 and CO2 monitor is also ideally suited to commercial manned submersible environmental monitoring.

Providing continual displays of the O2 and CO2 content in the enclosed space of a submersible with adjustable alarms and datalogging, what more could you need?


The Sub Aspida is a portable oxygen and carbon dioxide monitor with a 'man down' alarm, audio/visual alarms, datalogging and dual battery flexibility.


Relatively small increases in the levels of CO2 can be harmful and can have health effects which could impair the pilot’s judgement during critical manoeuvres. Maintaining safe O2 levels is also vital for working safely under water. The Sub Aspida provides a quick response so that immediate action can be taken.


The Sub Aspida is commonly used in a submersible, clipped onto the operator panel but can just as easily be worn on the belt by an operator.
