  • Digital direct reading grain moisture tester
    Patent number: 4584522
    Abstract: A direct measuring digital grain moisture meter comprises a light weight power supply, an oscillator, a two plate capacitor having a receptacle admitting a grain sample acting as the capacitor dielectric, and a detector/display measuring the dielectric constant and hence moisture content of the grain sample and displaying a numeric representation the moisture content of the grain. The meter provides a direct reading of grain moisture content requiring no further mathematical manipulation by the user or external temperature compensation.
