This meter works quickly to give accurate results on its clear, easy-to-read analog display, which includes a built-in wood scale and a numerical reference scale for measuring relative humidity in non-wood building materials.
The Delmhorst BD-10's pin-type meter uses two pins that penetrate wood and other building materials to a depth of 5/16 inch. Pin-type meters provide more accurate readings than surface meters because their tips come into direct contact with the material being measured. If you ever deal with materials that have been exposed to surface moisture, a pin meter is the best measurement tool because its readings are not skewed by this factor.
Plus, the Delmhorst BD-10 is built with a special connector for an external electrode, such as the Delmhorst 26-ES (sold separately), which allows you to take surface and core moisture content readings to a maximum depth of 1-1/16 inch.
The Delmhorst BD-10 is backed by a one-year warranty.
