What Is an Air Permeability Tester?
An air permeability tester is a professional textile testing instrument used to measure the ability of air to pass through fabrics.
During testing:
The specimen is securely clamped.
A controlled pressure difference is created.
Air passes through the fabric.
The instrument calculates the air permeability value automatically.
Testing purpose:
Evaluate wearing comfort and ventilation performance.
