The Technique of Duff Hygrometer Calibration
Abstract:The duff hygrometer devised by the Forest Products Laboratory is now widely used to measure the moisture content of the duff. Because of the fact that duff moisture content must be known accurately in order to evaluate fire danger, duff hygrometers must be carefully calibrated. The technique of calibrating these instruments requires care and considerable time. Users of duff hygrometers undoubtedly will he interested in knowing precisely how they are calibrated.
