[PSUBS-MAILIST] pp02 - %02 monitoring

[CCN Prepress <ccnprepress@ccn.co.nz>]

Hello to the group

I'm currently looking for monitoring equipment for cabin environment.

www.Oxycheq.com/ seem to have all the bits required to build a analyzer all
at a resonable price.

Patrick at Oxycheg tells me "For this application, I would set the meter to
read PPO2 as opposed to % oxygen". (application being dry ambient pressure)
 
Without sounding to thick, the question/information I'm looking for really
is what does this mean and what is resonable pp02 levels (normal-min) for
life support.


Thanks all for your time
