Re: [PSUBS-MAILIST] Which gases to detect?
Your nose is a pretty good chlorine detector, even at low
concentrations. Ditto hydrogen sulfide (AKA rotten egg gas). Carbon
monoxide is odorless, and dangerous in very low concentrations. I would
vote for CO as the "extra" gas.

I've been looking into gas monitors, and have found what I think is a
good one for the lowest cost. What I'm interested in monitoring is O2
and CO2, but the instrument monitors four gases in total. The question
then is, if I'm going to get two extra gases monitored for the same
price, do any of the available combinations present some advantage for a
sub? Here are the "extra" gases to choose from:
- Carbon monoxide and hydrogen sulfide
- Ammonia and sulfur dioxide
- Ammonia and chlorine
- Carbon monoxide, ammonia
- Carbon monoxide, sulfur dioxide
- Carbon monoxide, chlorine
- Hydrogen sulfide, ammonia
- Hydrogen sulfide, chlorine
- Sulfur dioxide, hydrogen sulfide
I'm thinking I could always use the carbon monoxide in my home when
checking for furnace leaks, and was it not chlorine that is produced
when sea water comes in contact with batteries? In that case monitoring
for chlorine might be useful in a sub that has battery pods that
communicate with the cabin.
For those interested, here is the manual describing this instrument:
