ABSTRACT:
A gas pressure gauge tester utilizes the pressure equalization perforations in the face of a gas pressure gauge to introduce pressurized gas into the gauge to counterbalance the gas pressure exerted on the gauge from the gas within a storage cylinder associated therewith. The gas pressure gauge to be tested is captured within a bracket which has integrated thereto a conduit connector cooperatively positioned to seal the pressure equalization perforations such that gases may be introduced thereto from a regulated supply of pressurized gas in order to counterbalance the internal pressure of the cylinder associated with the gauge. The amount of pressurization necessary to counterbalance the gas pressure is indicative of both the operability of the gauge and the state of charge of the associated cylinder.
