Abstract
A multiple-gain, hand-held, near-infrared grain analyzer analyzes, e.g., protein content of grain by infrared transmittance and interactance (transflectance) has at least two gain values. A first gain value is used when calibrating the analyzer with an empty analysis chamber (empty except for the presence of air), and a second, higher gain value is used when analyzing grain samples.
