Abstract
The invention belongs to the area of material research and analysis, specifically among electrical methods for determining wood m isture content, and can be used in moisture contents above the fibre saturation point. Moisture meter with the electric loading effect above the fibre saturation point of wood enables on-line registration of temporal patterns of wood electrical resistance and electrical capacitance as well as saving these in the memory of a microcomputer in the course of the wood electrical charging cycle at a previously set measuring speed. After the measurements have been carried out, the file containing calibration model and a prognosis of wood moisture content is presented along with the estimated statistical error. The distinctive characteristic of the method of calibration of the moisture meter with the electric loading effect above the fibre saturation point of wood is the occurrence of a significant decrease in the uncertainty of measurement as wood moisture content increases when moisture levels above the fibre saturation point are measured. The decrease in the uncertainty of measurement, especially in high wood moisture contents of 100% and above, is achieved by the original application of the wood charging number and consideration thereof in the compilation of the calibration model.
