Abstract
In a process for measuring the equilibrium moisture in hygroscopic, laminar material coated on both sides, preferably in raw paper coated on both sides used as support for a photographic paper, by determining the relative moisture of the air in contact with the material, samples are removed from the material by a process which forms cut surfaces on the material and are introduced into a container which can be sealed off against the outer atmosphere, and after establishment of the equilibrium moisture in this container the relative moisture of the air contained therein is measured.
