The Ligno-Scanner SD pinless moisture meter indicates true wood moisture percentages corrected for different wood species. Wood species and corresponding settings are listed on a laminated species card included with each moisture meter. Wood species corrections can also be custom-programmed by entering the specific gravity between 0.3 and 1.0. A reference scale has been added to allow comparing different moisture levels in laminates and building materials, useful when searching for high moisture levels in walls, ceilings and floors after water damage.
Another pinless advantage: Pinless moisture meters from Lignomat measure lower moisture contents than pin meters for hardwoods. A great advantage for the flooring industry in areas of low relative humidity and high desert climate zones.
