Product Description
The digital automatic polarimeter is a high‑precision optical analytical instrument for measuring the optical rotation of optically‑active substances. It automatically detects the rotation angle of polarized light passing through samples, and calculates specific rotation, concentration, purity and sugar content according to built‑in formulas. Widely applied in pharmaceutical, sugar, food, chemical and fine‑chemical industries for quality inspection, component quantification and raw‑material purity verification. It features automatic measurement, fast response, digital readout and high repeatability, reducing manual operation errors.
