DRK8066 Automatic Polarimeter

The drk8066 automatic polarimeter is a new product developed by our factory. Its characteristic is to use a high-efficiency LED lamp with a lifespan of more than 5000h as the light source, instead of the short-life, easily damaged sodium lamp and the high-temperature halogen tungsten lamp. This greatly eliminates the user’s inconvenience in use due to frequent replacement of the sodium lamp. Another feature of the instrument is that the temperature of the sample chamber can be kept consistent with the ambient temperature, avoiding errors and inconveniences caused by the temperature rise of the sample chamber. It has four test modes of optical rotation, specific rotation, concentration, and sugar content. It can automatically repeat the measurement 6 times and calculate the average value and root mean square. It can display sample temperature and can measure dark samples.
