Abstract
A portable grain moisture meter has a large 16 character digital display allowing an alphabetical list of grain selections to be selectably displayed in full text format and subsequently tested for moisture content with the test results also displayed on the same display. The meter also has provisions for calibrating the meter to a remotely located meter.
Claims12
A portable grain moisture meter comprising:
- a 16 character digital display for displaying a full text readout;
- a test cell for holding a predetermined volume of grain to be tested;
- capacitance circuit means for measuring the moisture content of the grain in said test cell and establishing a signal indicative thereof;
- memory means for storing a full description of various grain varieties including the grain being tested and establishing a signal indicative of the grain being tested;
- and
- computer means for processing said signals from said capacitance circuit means and said memory means to establish a control signal to said 16 character display to display the full text description of the grain being tested and the moisture content of same.
