High-Speed Automatic Polarimeter - Digital Polarimeter with Peltier Control - ±90° Range - 8°/s

The Master Science High-Speed Automatic Polarimeter is a five-model series built on a digital platform. A high-precision photoelectric encoder takes the place of the worm gear found in conventional polarimeters, which simplifies the mechanics, raises measuring speed and keeps the instrument quiet.

All models measure optical rotation, specific rotation, concentration and international sugar scale over ±90°. Response speed is 8° per second, with six readings averaged in 26 seconds. The upper three models run an Android system on a 10.1-inch touch screen; the other two use an 8-inch touch screen.
