To improve the accuracy of resistance-type moisture meters for wood, statistically confirmed moisture/resistance characteristics in the moisture range between 6% and 30% MC for seven important commercial wood species (beech, oak, spruce, pine, dark red meranti, sipo and teak) were determined. The analysis of these characteristics showed a difference of up to 3.2% MC between species of the same group arranged by the resistance-type moisture meter manufacturers. With regard to the moisture/resistance characteristics the accuracy of this measuring method is estimated on a 95% confidence level. In the hygroscopic range beech, oak, spruce, pine, sipo and teak are reliably measurable with a accuracy between ±1.0% and ±2.0%, while dark red meranti with a measuring error of about ±3.5% is scarcely measurable with the necessary accuracy.
