    摘要： A moisture meter for determining a rate of water content of a grain sample (4) by measuring the electric capacitance of the sample placed between a pair of electrodes (2,3) produces a rate of water content corrected for error due to the weight variation of the sample from a standard weight. The weight of the sample is determined by measuring the capacitance between an electrode (51) mounted to a spring balance (51, 53, 54, 55) on which the sample is placed, and another electrode (52). This capacitance is combined with a fixed inductance L and thereby converted to an oscillation frequency corresponding to the weight. The oscillation signal is counted and digitally processed for use in correcting the rate of water content.
