I ordered one of these yesterday from my local NAPA store and it will be available for pick up later today. After I get it I'm planning to take it to a truck tire shop and get it calibrated for accuracy. The guys at the tire shop steered me towards this one at NAPA, as the last gauge I bought and took to them for testing was reading 106 PSI at 100 PSI (like most, non-adjustable), so I returned it.

Does anyone have a better idea to obtain correct PSI readings?
If you have a bigger budget I purchased two powertank digital TIG 8340 kits. 1% accuracy. Six foot hose for safety. Front and outside tires can use the clip on end.
Obviously a pro grade tool.
Someone here linked this long ago. Thanks.
Regarding my thread; Sample Request for Wilkerson Corporation (http://solutions.parker.com/wilkerson-pressure-gauge-sample)
Says it's accurate to 1% at full scale (145 PSI) with 1/4" NPT-M threads, so I may hook my free sample to an air chuck and have another
reliable tire gauge.
That gauge looks a lot like this one I bought not long ago. So far I like it a lot. Says 2% accuracy.
