CO detector

I wonder if a simple domestic unit would do from a DIY store which has a readout & several ppm levels of alarm eg http://www.safefiredirect.co.uk/carbon-monoxide-detectors/co-9d-digital-7-year-carbon-monoxide-alarms.aspx

 

are you concerned about leaks into the interior? This is the first time I've heard anyone ask for a portable CO detector.

 

I haven't used this particular device, but I've used their "Colourtunes" and was pleased with them.

This unit just measures CO. More professional hand-held units will measure the full spectrum of gases (but add another zero to the end of this price for those)...

You mean for exhaust gases?

I suggest IRI. Very nice equipment.

I believe that the marine electronics department on level 3 has what you are looking for. I remember on a friends yacht several permanent ones down below deck and remote monitors above.
