Oxygen Permeability Tester

PT311 Air Permeability Tester is applicable in the measurement of air permeability rate, at various temperatures of plastic films, laminated films, high barrier material, sheets, foils and rubber, including breathable film and tyre seal performance, etc.

Put the pre-conditioned specimen between the upper chamber and chamber, clamp it tightly. First vacuumed the low-pressure chamber (lower chamber), and then the whole system. When the specified degree of vacuum is achieved, shut off the lower test chamber and feed test air to the upper test chamber (high pressure chamber) until certain pressure is reached. Ensure that a constant differential pressure (adjustable) is maintained across the specimen. Hence under the gradient of differential pressure the test air 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.
