WZZ-2A/WZZ-2B Automatic Polarimeter
Intended use:
The polarimeter is an instrument used to determine the optical rotation. Through the measurement of optical rotation, the concentration, content, and purity etc. of a substance may be analyzed and determined. It is broadly used for assay or process quality control in departments of industrial production, scientific research, and education concerning pharmacy, drug control, sugar manufacturing, food, flavor, chemical industry, and petroleum.

Characteristics:
With technology of photoelectric detection and micrcomputer control, as well as large-screen backlit LCD display, the data is visual and clear. The optical rotation may be automatically measured for 3 times, and then the average may be worked out. For the WZZ-2B Automatic Polarimeter, there is a RS232 interface for sending the data to PC.
