ABSTRACT:
An improvement in devices for determining the moisture content of lumber by measuring the electrical resistance of the wood. A biasing system is provided so that the voltage supplied to the electrical contacts disposed in the wood may be adjusted. This arrangement allows for corrections to be made in the electrical operation of the device, which corrections compensate for anomalous properties of the wood.
