A method and device for using a permeameter comprising a measuring head (2) opposite which the sheet or strip (1) is displaced step by step. The method and device can comprise a registration including the determination of the permeability profile of the strip (1) over a period T including two different successive permeability ranges, determination of a sinusoid from said profile, the of two extremes of said sinusoid, centering the measuring head (2) on the second extreme, and moving the strip step by step by T/2 and, at each step, performing a permeability measurement.
