Abstract
A pressure testing device comprising a connector adapted to engage a gas line containing a gas supply under pressure is provided. The pressure testing device includes a measuring device and a compressible pump. The measuring device operably communicates with the connector and is responsive to variations in pressure of the gas supply. The compressible pump has an input port and an exhaust port. The input port is adapted to receive ambient gases and the exhaust port is adapted to communicate with the measuring device for delivering ambient gas pressure to the measuring device.
