Determination of Moisture Content of Wood by Pulsed Nuclear Magnetic Resonance
Keywords:Picea glauca, Acer saccharum, nuclear magnetic resonance, moisture content, moisture meters
AbstractPulsed nuclear magnetic resonance techniques have been used to measure the moisture content of sugar maple and white spruce sapwood in the range from 0 to 176%. The technique is found to be complementary to other methods of measuring moisture content in wood-cellulose systems.
