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 is generally used in pharmaceutical, perfume, cosmetic, industrial, chemical, and food factories. It is one of the best methods for measuring the angle of rotation. In addition, the built in International Sugar Scale is used widely in sugar factories. This product comes standard with a two (2) year limited warranty against manufacturer’s defects from the date of the original purchase. The warranty period can be extended to three (3) years if the product is registered with ATAGO.
