Air Permeability Tester STD-F8


The Air Permeability Tester is a high-precision instrument designed to measure the breathability of materials, ranging from highly permeable gauze to waterproof breathable fabrics. It provides fast, accurate results using a digital display to eliminate manual reading errors. With a pressure measurement resolution of 2 Pa, this instrument ensures high-precision data, making it ideal for textiles, building materials, hygiene products, and related industries.

Application

The Air Permeability Tester can evaluate a wide range of materials, including:

Textiles: gauze, stockings, socks, underwear, cotton, and other fibers.

Hygiene products: adult diapers, sanitary napkins, and medical nonwovens.

Building materials: insulation materials, breathable membranes.

Cosmetic packaging materials.

Waterproof breathable fabrics.
