This unique device can be used to test SCUBA regulators for inhalation/exhalation effort plus first stage intermediate pressure and lockup stability. All tests can be done without dismantling the regulator. To check intermediate staging pressure, merely attach the BC hose to the testers inlet fitting, pressurize the regulator, and read the gauge. A push button vent allows rapid cycling of the first stage for repeated testing or depressurization after completion of testing.
