A non-penetrating LCD moisture meter with tricolor bar graph and backlit display, model MMD7NP, is available from General Tools & Instruments.
The meter is ideal for measuring the moisture content of wood and differentiates between hardwood and softwood, according to the company.
It can also be used for measuring the moisture content of drywall, masonry or concrete; detecting moisture below the surface of carpets and subflooring; and locating water leaks above ceilings, below floors or behind walls.
It has a maximum sensing depth of 3/4” (20mm). As a pinless model, the instrument acquires readings via a non-invasive method, which means it will not mar wood or other materials, a paramount concern when trying to detect moisture under a finished surface.
