The basic scientific instrument used to measure angle of rotation, specific optical rotation of optically active substance.

The polarimeter is a kind of instrument for measuring the optical rotation of a substance. Through measuring the optical rotation, the polarimeter can be used to analyze the concentration, content, and purity of a substance. The WZZ-2A automatic polarimeter utilizes the photoelectric utilizes the photoelectric detection automatic balance principle and the results are displayed by LCD. WZZ-2A automatic polarimeter is characterized by its small size, high sensitivity, easy reading, and so on.

Furthermore, this instrument is also suitable to the sample of low optical rotation which is difficult to be analyzed by visual polarimeter. Therefore, it can widely be used in various fields of the organic chemical industry.

Agriculture: use in contents analyses of agricultural antibiotic, hormone, microbial agro- pharmaceuticals and agricultural products.

Medication: use in analyses of antibiotic, vitamin and glucose and in pharmacological research of Chinese medicinal herbs.

Food: use in analyses of sugar, monosodium glutamate and soy sauce, in inspection of their final products and determination of sugar content in food.
