The Timber Moisture Meter GMK 210 is the ideal tool to quickly locate moisture not only in buildings, but also on boats or in caravans. The measuring method of the Timber Moisture Meter works absolutely non-destructively. The evaluation simultaneously occurs both acoustically and visually. The Timber Moisture Meter is simply held against the surface which is to be examined. The non-contact capacitive measurement process can determine whether there is increased moisture up to a depth of about 25 mm and thus if a more detailed investigation is required.
