[PSUBS-MAILIST] O2 sensors

[Marie-Andrée et Pierre <poulin.carrier@videotron.ca>]

Hi guys,

After seing Jon's presentation at the convention I decided to go with a 
scrubber and a O2 injection device.

My question is: Will an oxygen sensor work for a dry-ambient sub? How does 
the sensor work? I know it give a different voltage outpout depending on the 
amount of oxygen in the air. but what happened when put under pressure? Will 
it track PPM of oxygen in the air or the % of oxygen in the air? Will it 
detect 21% at 1atm, 42% at 2atm, 176% at 5atm, etc...

Does anybody here have experience with a scrubber/O2 system in an ambient 
sub?

The reason I decided to go scrubber/O2 is that I have about 35-40 minutes 
inside my sub before I feel the effect of too much CO2 in the cabine. If I 
refresh the air inside the cabine by injecting fresh air from my tanks, it 
is not very effective and takes alot of air.

Thank you all!

Pierre "O2" Poulin
