Abstract
Wood contains different mass ratios of water so determining the moisture content of wood is important information for monitoring the condition of a living tree through the process of drying and preparation of the raw material throughout the entire exploitation life of the wooden product. Wood is a dielectric by nature, but it conducts electricity thanks to the presence of water. The electrical resistance of wood is strongly correlated with the amount of moisture contained in the wood itself, along with the specifics of the variety and other parameters. Special instruments, hygrometers can be used to determine moisture in wood, or standard methods of measuring electrical resistance can be applied. In this research, a Trotec T2000 moisture meter with an external temperature probe was used to measure moisture in two different types of wood under different conditions. Measurements were made at different input temperatures of the instrument for known resistances and the influence of temperature correction of the instrument on the measurement result. At the same time, the influence of the measurement
directly on the measurement result and the value of the measured moisture in dependence on the measurement depth was observed.
