A special hose assembly that connects a standard scuba cylinder to the Bulkhead Air Shunt port of Global's Test Chambers (#48300 / #48310) that allows the pressurization of any air integrated computer connected to high pressure swivel inside the chamber. The threaded port of this swivel will accept the hose of any fully integrated dive computer which then can be submerged in the chambers water-filled bucket and tested as follows: After the computer is activated at full tank pressure, any lesser pressure can be obtained by turning off the tank and using a bleeder to vent down to the desired level read on the connectors integrated gauge. Note: The chamber itself must be pressurized with a separate air tank. In this manner, integrated computers can be tested at virtually any combination of simulated depth and diver air supply! Another special adapter (Global #48302) allows the testing of hoseless computers. The Bulkhead Air Supply Connector consists of a standard yoke connection with a ported bleeder block with a 5000 psi gauge and a 5ft. hose that mates to the Air Shunt port.
