The importance of moisture control of lumber and other wood products for various uses cannot be overemphasized. Moisture content control in the processing and fabrication of consumer items of wood requires a rapid and reliable means of moisture determination. Four methods of wood moisture content determination are described herein: One, the electronical method, is non-destructive and practically instantaneous; the other three, namely the oven-drying method, a distillation method, and a hygometric method, are destructive in that they require that the lot be sampled for specimens that are subsequently analyzed for moisture content.
