I use a Teledyne O2 analyzer here at NOAA. We always calibrate to
21%. I've never heard of anyone calibrating to 100% O2, although I'd
guess it would work. It just seems like an extra step to take, a
little more complex, and unnecessary.

Went to Ginnie this weekend and dove 36%O2. We got refills at a local
shop and the fellow calibrated the Miniox sensor by running "100%" O2
across the sensor. We were shown in the ANDI class to calibrate to
~21% in the surrounding air. I asked the filler if the sensor gave valid
readings all the way from 1% to 100% and he gave me that..."youre a
dumbass look". Obviously filler boy has never pondered the question...
What is the best way to calibrate the sensor short of
calling Miniox and asking for specs for the sensor? Is this gizmo affected
by other factors like temp or humidity?
