I don't know, and frankly for $1 each, I doubt they are accurate. But that begs the question, why would someone want to have their tire gauges calibrated? How is a calibrated gauge going to outperform my $1 pencil gauge for a daily driven car with no special needs or wants?
At one point recently I realized I had a stack of pencil gauges, so for fun I picked a tire and tested them all against each other. I tossed several that seemed to be more than a few pounds off from the others. Now I'm left wonder if any of them are all that good! better than nothing but nothing i'd trust to 1psi. [Not that I am that picky about it, most of my tires seem to wear ok where they wind up for pressure.]
