The aim of this paper is to present the methodology of measurement of moisture content of wood and show some results of this measurement in application on small pieces of wood. Fresh wood from the tree has rather high content of moisture, which makes it not suitable for use in constructions or industry processing. The usual drying methods are based on drying with lower air temperature, and the drying process lasts long time. This paper describes the theory and experimental results of wood drying by high temperature of 105 ºC. Using the experimental data with the natural convective drying method in the laboratory conditions under high temperature there were calculated the theoretical drying coefficients, useful for description and modelling of the drying process, the calculated theoretical results of moisture removal and compared with the experimental results obtained from the measurements. The obtained results of this research are parameters, which can be used for other research work and for improvement of the whole drying process.
