Abstract
A method of determining the presence and quantity of wood treatment substance (pesticides, water repellants, dimension stabilizers and the like) on wood is provided. The wood treatment substance is combined with a fluorescent material and applied to wood. A light beam is impinged on the wood, and reflected light measured by a spectral device. Color saturation level of the reflected light is determined with a microprocessor. From this measurement a quantity of wood treatment substance on the wood can then be determined.
