Air Permeability Measurement Device

The air permeability tester measures the gas transmission rate of materials using the differential pressure method. It creates a stable pressure difference on both sides of the sample, allowing gas to permeate from the high-pressure side to the low-pressure side. Sensors record pressure changes to calculate the air permeability. It is used to test the barrier properties of materials such as plastic films, paper, and coatings, ensuring the sealing quality of packaging.
Selection
When selecting, consider the material type in relation to the testing standards: choose a low-pressure range for thin films and a high-pressure model for thick materials. Confirm that the test gas type matches the sensor. Select manual or automatic models based on production needs. Verify the validity of the instrument's calibration certificate. Compare the test chamber size to ensure it is compatible with the sample specifications.
