Our local Firestone Tire dealership has been kind enough to "check" all my pocket air-pressure gauges for me...checked against their *master* pressure regulator which they have checked/measured/calibrated every six months. They have a "T" shaped fitting that chucks onto their line while my gauge(s) connect onto one of the other two fittings...and we compare the numbers.
