Air Permeability Tester

The air permeability tester uses the gas pressure difference method to create a stable pressure difference on both sides of the sample, measuring the gas transmission rate. It is used to detect the air permeability characteristics of materials such as films and paper, and is applied in quality control of packaging materials and performance evaluation of protective equipment.
Selection
When selecting, focus on the test range covering the actual sample air permeability, ensure the instrument complies with ISO, ASTM, and other standard methods, consider testing accuracy and repeatability indicators, adapt to sample thickness and size, and evaluate operational convenience and data output methods.
