A system for analyzing agricultural products on harvesting equipment includes a test chamber and a near infrared spectrometer disposed within a housing capable of being mounted on the harvesting equipment. A source of near infrared radiation is disposed in the housing adjacent the test chamber so as to emit near infrared radiation into the test chamber, and a near infrared detector is disposed in the housing adjacent the test chamber so as to receive near infrared radiation exiting the test chamber. The spectrometer is mounted on vibration damping elements. A computer controls operation of first and second doors for controlling ingress and egress of product samples from the test chamber and can also be used to process signals from the spectrometer.

System and method for analyzing agricultural products on harvesting equipment

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.
