ABSTRACT:
A moisture tester is provided for testing a sample of feed of the silage, haylage, and like compressible variety. The tester includes a chamber for receiving a feed sample. A compressible piston compresses the feed sample in the chamber to a predetermined density to provide accurate, reliable, reproducible results. The chamber comprises spaced electrodes constituting a capacitor such that the dielectric constant of the capacitor is modified in accordance with moisture within the feed sample. A circuit functionally including the capacitor develops a signal in accordance with the moisture content of the sample. A readout, responsive to the circuit signal, provides a visual indication of the feed sample moisture content. A circuit trigger is automatically operated by the compression exerted upon the feed sample to start circuit operation and provide the feed sample moisture content readout.
