Method for measuring film thickness on wood panels using an IR analyzer

摘要

A method of manufacturing paneling and the like in which the thickness or weight of coatings applied to substrate materials is measured by infrared absorption providing a digital representation, accurate to 0.01 mil, of the coating's thickness or weight to 0.01 gram/sq. ft. The rate of application of the coating is adjusted in accordance with the measurement to maintain the coating weight or thickness within optimum limits.
