The PMI fully automated Advanced Bendsten Permeability & Surface Roughness Tester is able to measure air permeability and smoothness according to standards ISO 28791-2 and permeability to ISO 5636-3 and 5 with digital display.
The Advanced Bendsten Air Permeability and Surface Roughness Tester is used to determine the permeability and surface roughness of porous solids. A gas such as air is forced to ﬂow through the test sample. Measurements of the steady-state ﬂow rate and the corresponding pressure drops provide the necessary data for calculation of the permeability using darcy and other units.
Industries worldwide utilize permeability and surface roughness testers for R&D and quality control.
