Dry basis moisture is most commonly used for measuring moisture changes in solid wood products. When measuring the moisture content of the wood on a dry basis, the weight of wood does not include any water. It is the weight of the wood after it is oven-dried. When wood loses or gains moisture, the change in the dry basis moisture is linearly related to the weight loss or gain. In simpler terms, in dry basis moisture measurement, the weight of the wood is a constant and the increase or decrease in weight is directly related to the amount of water the wood contains. Moisture content measured on a dry basis can exceed 100%.
