Characteristic
The instrument applies the unique and state-of-art control technology, equipped with high quality prisms. It not only greatly enhances the response speed, measurement time, and minimum transmittance when the polarimeter is testing samples, but also fuuly embodies the high speed, efficiency and accuracy features, which completely transformed the slow response speed and long measuring time of the traditional polarimeter. It’s a landmark’s breakthrough of polarimeter development in China. In terms of function, the user can customize up to 300 commonly used measurement methods which are pre-stored in the system. With applying the latest IT technology, the instrument can access the Internet.
