Due to covid-induced boredom, I recently dug out some of my old air pressure gages, and ran some back-to-back measurements, comparing them to the current favorite. Readings were all over the place.
Some of the pencil styled gages had obviously gone bad with readings off by 10-15 PSI. Tossed them. But some of the newer, preferred gages also didn't agree very well; differences of 3-4 PSI.
Since retiring, I've lost my access to a commercial gage calibration machine, so I'm at the mercy of whatever gage I decide to use.
Wondering what you guys do? Do you have gages that you like and trust?
