The DigiPol-R series of fully automatic laboratory refractometers is equipped with a high-performance linear CCD sensor. Utilizing high-speed, high-precision signal acquisition and analysis technology, it features a semiconductor Peltier super temperature control system. It can efficiently and accurately measure the refractive index (nD) of various liquids—including transparent, translucent, dark-colored, and viscous liquids—as well as the mass fraction (Brix) of sugar solutions.
These laboratory fully automatic refractometers are widely used in the petroleum, oil and fat, pharmaceutical, food, daily chemical, and sugar industries, and are also common equipment in schools and related research institutions.
Peltier temperature control, high precision, and high stability.
7-inch touchscreen with a user-friendly interface for easy operation.
High efficiency and precision for accurate data measurement.
Complies with national standards, quality guaranteed.
