         Here is your solution.  Imperial Supplies has calibrateable tire 
gauges

http://www.imperialsupplies.com , under Hardware, Tire Hardware

Calibratable gauges:

They also have an Air Gauge Test Station:

http://www.imperialsupplies.com/item/0739570  (includes video of 
calibration procedure)

This could be fabbed up fairly easily.  A piece of pipe with ends welded 
up, a port with a regulator for filling the pipe with air at a specific 
pressure, a port fitted with an accurate test gauge (McMaster has 
High-Accuracy Gauges that would work) and a Shader valve to attach the tire 
gauge you want to test.
