Zusammenfassung:	The present invention relates to an arrangement for determining the permeability of a sample, said arrangement comprising a source of fluid medium arranged such that at least a fraction of said medium can be brought into contact with a first surface of said sample to be tested; means for measuring the electrical properties at a second surface of said sample, wherein the second surface is opposite said first surface of said sample; and a controller for recording said electrical properties, and for determining the transmission rate of the fluid medium through the sample based on the recorded electrical properties.
