Air Permeability Tester is used to test the air permeability of textiles or other material, such as carbon paper.

A specimen placed on a standard test area of air passage, a pre-set of air flow on both sides of fabric which occur a differential pressure and this tester calculates the air permeability of fabric by the test area and differential pressure result automatically.

1.     RF4308EP Air Permeability Tester included testing device, different size of test heads, vacuum pump and micro-computer.

2.     Control the pressure difference between the two sides of the specimen accurately.

3.     Automatically calculate the air permeability index.

4.     Touchscreen operation.

5.     Testing ranges automatic selection.

6.     PC software for data collection and testing report output.

7.     GB/T20042.7-2014 test method is built in.
