Application:
The Polarimeter is an instrument used for determining the optical rotation of substances. In this way, the concentration, content, purity, etc of certain substances can be found out. Therefore, the polarimeter has become one of the most useful instruments in laboratories of sugar industry, pharmaceutical industry, oil refining, foodstuff industry, chemical industry, universities and scientific research field.
Characteristics:
* Use the incandescence lamp plus filter stand for sodium lamp in order to lengthen the service life of the light power ( more than 2000 hours) .
* 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.
* Sample chamber adopts constant temperature heating effect on measurement.
* Temperature display and USB interface.
