Abstract: A probe for measuring the moisture content of wood in the center of a stack of wood has a moisture content sensor near a first or forward end thereof. The forward end of the probe is bendable and in one form is articulated. An extendable member also is mounted at the forward end of the probe. The extendable member is pivoted by a slide handle at an opposite end of the probe between reclined and extended positions. The forward end of the probe is inserted into a stack of wood between layers of the stack. The extendable member is extended to press the sensor against wood in the center of the stack. A meter connected to the sensor then registers the moisture content of the wood.
