The Air Permeability Tester Digital monitors the permeability of textile fabrics including woven, non-woven, airbag fabric, blankets, napped fabrics, knitted or layered fabrics and pile fabrics.  The principle of the Air Permeability Tester is that air is drawn through a specified area of fabric, which is adjustable to suit specific textiles being evaluated.  

It is a fast and easy to use instrument, useful for quality control.  With its digital operation, you are able to test and inspect incoming material, and enable precise and repeatable testing.  It has a digital flow range of 5-500 L/min, and a digital manometer of 200-2000 Pa.  It also features a variable flow range, and a test head area of 38cm².  Different sized test head areas are also optional.

The Air Permeability Tester Digital is manufactured with reference to ASTM D737 standard.
