Moisture Meters for Wood, Concrete, and Building Materials

Pin-type meters read moisture by driving two small needles into the material and measuring resistance between them, which gives a direct percentage reading but leaves small puncture marks behind. Pinless meters scan the surface instead, using electromagnetic signals to read moisture below the surface without marking the material, a better fit for finished wood, drywall, or anywhere visible pin marks aren't acceptable.

Concrete testing works differently from either of those. A relative humidity probe gets inserted into a drilled hole in the slab and left to equalize, giving an in-situ reading of moisture deep in the concrete rather than just the surface. That reading matters most before installing flooring, since a slab that tests above the flooring manufacturer's moisture limit can cause adhesive failure or cupping if it's covered before it's actually dry enough.

Protimeter supplies nearly everything on this page, spanning pin-type meters, pinless meters, relative humidity probes, and the sensors and parts that go with them. Taylor Tools adds Delmhorst branded pin-type meters as an additional option.
