Electrical methods of assessing the moisture content (MC) of wood are commonly employed by the wood-using industries. These methods make use of such electrical properties of wood as its electrical resistance, dielectric constant, and radio frequency power loss which vary with MC. Moisture meters using the relationship between MC and resistance are known as the resistance-type; those which use the relationship between MC and dielectric constant are the capacitance-type; and the meters using the relationship between MC and radio frequency power loss are the RF power-loss-type. In the lumber industry of eastern Canada the resistance-type meter is used almost exclusively.
