Sensitivity of handheld dielectric moisture meters to a wet core
1991
Quarles, S.L.
The sensitivity of power-loss and capacitive-admittance handheld moisture meters to wet core regions was investigated. Results showed that the capacitive- admittance moisture meter was more sensitive to the presence of wet core regions. The power-loss meter readings consistently indicated the moisture content of the surface region regardless of the proximity of the wet core to the surface. Consequently, results suggest that the electrical field penetration is greatest with the capacitive-admittance meter. Neither meter, however, could predict the occurrence of wet cores at a depth of 1 inch, and therefore neither meter could be reliably used to detect wet cores in thicker material.
