SGWzz-2 Automatic PolarimeterDetailed product description：

The SGWzz-2 automatic polarimeter (hereinafter referred to as the instrument) features a light-emitting diode (LED) red light source with a service life of over 20000 hours as the light source, replacing the previously short-lived and easily damaged sodium lamps and high-temperature halogen lamps. This greatly eliminates the inconvenience caused by frequent replacement of sodium lamps for users. It has four testing modes: optical rotation, specific rotation, concentration, and sugar content. It can automatically retest 6 times and calculate the average and root mean square value; Can measure dark colored samples. The temperature control device inside the instrument has heating and cooling functions. If a temperature controlled test tube is used, the sample rotation can be measured for temperature control. The large screen LCD display on the instrument provides a human-machine dialogue menu operation method, which is simple, intuitive, stable and reliable.
