YJ-7100F Automatic Polarimeter

I. Main Applications:

A polarimeter is an instrument used to measure the optical rotation of substances. By determining the optical rotation of a sample, the concentration, purity, sugar content, or composition of the sample can be ascertained. It is widely used in sugar production, pharmaceuticals, drug testing, food, fragrances, monosodium glutamate, as well as in industrial production, scientific research, and educational sectors such as chemical and petroleum industries for化驗 analysis or process quality control.

II. Features:

Utilizes the photoelectric detection automatic balancing principle, with automatic measurement results displayed on a dot-matrix LCD. Newly added four measurement modes: optical rotation, specific rotation, solution concentration, and sugar content. Capable of automatically repeating measurements 6 times and calculating the average and root mean square. Equipped with an RS232 interface for data transmission to a PC.
