Hi all, This is probably going to be a stupid question but, I'm trying to get a reference on a pressure/temp gauge on an old pressure canner.
I've hooked up a bicycle pump via a tire valve & hose to the pressure canner & the pressure canner reads 15 PSI and the bike pump reads ~12.5 PSI at room temp. I've also checked the bike pump pressure gauge against a new spare pressure gauge & they seem to be within ~1 PSI.
My question is, will the steam/temperature affect the pressure cooker gauge differently than just pumping it up with room temp. air?
I know I should just go buy another gauge, but I really like the looks of the needle/indicator face of the old beast!
Opinions on bourdon tube "home re-calibration"? ;-)
