Air Permeability Tester

What is An Air Permeability Tester

The Air permeability tester measures the fabric’s ability to allow air to pass through. This air permeability is crucial for applications properties that depend on a fabric’s air permeability. For instance, in outdoor apparel, high air permeability might be desired for comfort, whereas in windproof or waterproof textiles, low permeability may be preferred.

Air Permeability Tester Featured Products

DaRong Developed several models of Air Permeability Testers for textiles, each with its specific features. You can always find a good fit for your laboratory to test the air permeability values according to different air permeability standards and air permeability methods.
