 Automatic polarimeters for more common laboratory applications
Automatic polarimeters are the basic scientific instrument used to measure angle of rotation, specific optical rotation of optically active substance. Built-in auto-controling system. Auto-judge substance from levorotatory or dextrotatory. 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.Specifications | Model | WZZ-2B | WZZ-3 | WZZ-2S | | Characterisctic | automatic servomechanism control | photoelectric test and microcomputer control | Measuring range
