摘要: A digital reading grain moisture tester is disclosed in which the frequency of an LC oscillator having as one element a capacitive cell containing measured weight material under test determined by counting number cycles occurring during period defined length. Circuitry provided to vary length compensate for differences physical properties grains may be tested and variations sample temperature. Automatic balance circuitry changes circuit parameters elements within tester.
