Automatic Polarimeter
SGW-2/SGW-1 Automatic Polarimeter
Characteristic
Need not prewarm when turning on;
Measuring specific rotation, optical rotation, sugar degree and concentration;
Automatic repetition-measurement for 6 times, and calculation of average value and means square root;
Peltier principle to control the temperature;
Measurement of dark-colored sample;
USB & RS232.
Features:
1. High-power light-emitting diodes are used as light sources, and the lifespan is more than 100,000 hours.
2. It has four test modes: optical rotation, specific rotation, concentration and sugar content. It can automatically retest 6 times and calculate the average value and root mean square. It can measure dark samples.
3. The built-in semiconductor Peltier device has heating and cooling functions. The temperature control test tube can be used to control the temperature of the sample to ensure the accuracy and stability of the test sample.
4. It adopts a large color touch screen to provide man-machine dialogue, which is simple and stable. Dual interface can be directed to
