Air Permeability & Mask Breathability Tester

Air Permeability & Mask Breathability Tester

Model:RF4308AP

Air Permeability & Mask Breathability Tester is an all-in-one tester for fabric air permeability and face mask breathability.

When doing air permeability test, 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.

When doing breathability test, a pre-set rate of air flow pass through the specimen. The pressure difference on two sides of the specimen is measured and serves as a scale for breathability.

RF4308AP includes testing device, different size of test head, vacuum pump and single processor machine, automatic control differential pressure and calculates air permeability.
