The DA 7300 is a diode array based NIR instrument designed for use in food and agricultural environments. It continuously analyzes moving products for parameters such as moisture, protein, fat and others. The analysis results are sent to a plant’s process control system for automatic plant optimization or are read out to a display screen for manual adjustment. The DA 7300 incorporates a real-time video camera with separate illumination for a unique view directly into the process. The video may be viewed on a computer attached to the system’s network – be it in the same building or thousands of miles away.
