This moisture meter from Lignomat USA is designed for measuring moisture without damaging the surface. It enables wood cabinet and furniture makers to choose the measuring depth; the feature is ideal when boards thinner than 3/4 in. are used, or when boards are not dried evenly, and the difference between core and surface moisture can be measured by toggling between ¼ in. and 3/4 in. deep.
