DRK8067 Automatic Polarimeter

The drk8067 automatic polarimeter uses light-emitting diodes as the light source, which avoids the trouble of frequent replacement of sodium lamps. The temperature control device in the instrument has heating and cooling functions. If a temperature-controlled test tube is used, the optical rotation of the sample can be controlled for temperature measurement. The large-screen LCD display on the instrument provides a man-machine dialogue menu operation mode, which is simple, intuitive, stable and reliable.
