This compact gas permeability tester determines the permeability of dry gases for packing materials using the manometric method. Under certain conditions moist gases may also be tested. The permeation at the bottom chamber of the test specimen is determined by the evaluation of the increase in pressure in the previously evacuated volume. The increase in pressure during the test period is evaluated and displayed by an external computer.
