Air PermeaMeter

The air permeability tester measures the gas penetration capability of materials using the differential pressure method. Under a fixed pressure difference, it records the amount of gas passing through a unit area per unit time, reflecting the material's barrier performance. It is used for testing the air permeability of materials such as paper, films, and non-woven fabrics, guiding adjustments in production processes.
Selection
Select the corresponding standard based on the type of material being tested (e.g., ISO 5636, ASTM D737). Ensure the instrument's measurement range covers the air permeability range of the sample, and the differential pressure accuracy meets the testing requirements. Consider automatic clamping and sealing designs, and ensure compatibility with the laboratory's power supply conditions. Verify the validity of the calibration certificate.
