Method and device for measuring the gas and/or liquid permeability in the surface layer of an object.

摘要

The invention relates to a method and a device for measuring the gas and/or liquid permeability in the surface layer of an object, especially for identifying wet storage damages on timber. The method implies that a gas or liquid via a nozzle is applied at pressure to the surface of an object, that the nozzle is applied with a certain force against the surface, and that the gas/liquid is caused to pass through parts of the surface layer. The pressure in the gas/liquid and the flow are measured and used as a measure of the permeability of the object.
