Abstract
A pressure gauge testing device comprising an air supply inlet; a pressure regulator connected to the air supply inlet; an isolation valve connected to the pressure regulator; a valve stem fitting connected to the isolation valve; and a pressure gauge for reading the pressure between the isolation valve and the valve stem fitting is disclosed. The device connects between an air source and a pressure gauge to test the accuracy of the pressure reading on the gauge. The device can also be used to measure tire pressure directly with the addition of an air connection fitting in parallel with the valve stem fitting/connection.
