Frazier Permeability Tester & Average Fiber Diameter Analyzer

The PMI Advanced Frazier Permeability Tester is able to calculate fabric resistance (woven, knitted and non woven textile materials) to the passage of air. The machine provides fast and accurate measurement of gas permeability of solid, cylindrical and sheet samples. Featuring nondestructive testing and fast results, our machine is perfect for both R&D and quality control. PMI’s Average fiber diameter analyzer (AFA) offers a simple, fast, and reliable technique for Average fiber diameter measurement - a measurement not readily achieved by static nitrogen adsorption (BET) methods. The AFA’s innovative use of flow permeametry combined with its sophisticated self-adjusting viscous flow controller enables testing of a wide range of powders and other samples, including materials with surface areas of only several square meters per gram.
