Air permeability Tester

Material Test & Measurement

Air permeability tester is professionally designed for the determination of air permeability of materials.

Full Description

Medical packaging, medical paper, polyurethane, expanded plastics, PVC, leather, textiles, nonwovens and other materials. Through the test, physical characteristics of materials could be controlled to meet practical application requirements.

Characteristics

1. This instrument is a touch screen operation, PLC control system, very convenient to operate
2. 2 test modes are available for customers: fix pressure difference to test flux and fix flux to test pressure difference
3. High precision sensors of electronic airflow and air pressure to ensure the accuracy of test data
4. Equipped with micro-printer

Principle

Method A
Providing a constant air flux going through the specimen vertically, the air permeability could be obtained by measuring the pressure difference.

Method B
Providing the constant pressure difference between two sides of the specimen, the air permeability could be obtained by measuring the air flux through specific area in the certain time.
