Actually if the place checking the gauge is competent, they are checking it against a gauge that had been calibrated and certified on at least an annual basis by a professional calibration lab. At my last job, part of my QA duties was to check the calibration/accuracy of the pressure gauges used on the production floor. I had to send the master gauges on the test fixture out for calibration every six months. They were checked against a master gauge which itself was checked against an NIST master gauge regularly.
thanx for bragging - I know - I've got a few masters and engineer for nearly a half century >>> this is a forum for preppers that just want to feel good about their pressure canner - nobody is recruiting here for MIT
you want to be some asshole prick - don't be using me or my postings for the purpose
