The AP-300 fully automatic polarimeter measures a sample easily by setting the observation tube (filled with a liquid sample) in the sample chamber and pressing START. Digitally displayed measurement values are large and easy to read. The AP-300 generally used in pharmaceutical, perfume, cosmetic, industrial, chemical, and food factories is the best for measuring the angle of rotation. In addition, the built in International Sugar Scale is used widely in sugar factories.
