2.Principle.
Put a preconditioned specimen between upper and lower chambers and clamp it tightly.
Firstly apply vacuum to the low-pressure chamber (lower chamber) and then the whole system.
When the specified degree of vacuum is reached, shut off the lower test chamber and feed test gas of certain pressure to the upper test chamber (high pressure chamber).
Ensure that a constant differential pressure (adjustable) is maintained across the specimen.
Hence under the gradient of differential pressure the test gas permeates from the high-pressure side to the low-pressure side.
By monitoring and measuring the pressure in the low-pressure side we can get various barrier parameters of the tested specimen.
