Fully Automatic Constant Temperature Polarimeter

YJ-7100K Fully Automatic Constant Temperature Polarimeter

A polarimeter is an instrument used to measure the optical rotation of substances. By determining optical rotation, it can analyze and determine the concentration, content, and purity of substances, and is widely used in industries such as sugar production, pharmaceuticals, petroleum, food, and chemical engineering, as well as in related universities and research institutions. It uses an LED as the light source, eliminating the need for frequent replacement of sodium lamps. The instrument's internal temperature control device features both heating and cooling functions. If a temperature-controlled tube is used, the optical rotation of the sample can be measured under controlled temperature conditions. The large-screen LCD display on the instrument provides a user-friendly menu operation interface, making it simple, intuitive, stable, and reliable.
