 Professional automatic polarimeters
Automatic Polarimeters use USB or RS232 and can be used for measuring specific rotation, optical rotation, sugar degree and concentration. It offers automatic repetition-measurement for 6 times, and calculation of average value and means square root. The automatic polarimeter uses Peltier principle to control the temperature. It can be used for measurement of dark-colored samples.Specification | Model | SGW-1 | SGW-2 | SGW-3 | Measuring range
