Extech Instruments recently announced the launch of the MO53 and MO57 pinless moisture meters. With the option of an integrated sensor (MO53) or an external spherical sensor (MO57), the new moisture meters make it easier to rapidly assess moisture content in lumber and building materials, without leaving pin marks.
Professionals rely on Extech's new meters for pro-grade moisture detection and measurements as deep as 4 in. while gliding the MO57's external spherical probe along a surface or up to 1 in. with the MO53's integrated sensor. The meters can be used to measure moisture in wood (up to 99.9%) as well as other building materials (MO57: 99.9%; MO53: 56.5%) such as wall board, sheetrock, plaster, mortar, concrete, and tile (using the MO57).
