Apparatus for the measurement of moisture in grain and other material. It weighs the sample as added, to ensure a constant sample weight; it dumps the sample in a predictable manner into a capacitive cell; it effects a capacitive measurement and compensates for the temperature of the specimen. The measurement of capacitance provides a measure of the moisture content. In order to compensate for variations in the volume of a weighed sample, arising from grain size, the capacitive cell is cylindrical in form and extends vertically, but lower parts of its metal walls are cut away to provide a lesser capacitance per unit height over the lower parts of the cell compared with upper parts of the cell.
