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.
Built-in Peltier temperature control for enhanced accuracy and stability.
Dual temperature control with a sapphire prism.
LED cold light source replaces traditional sodium lamps and halogen tungsten lamps.
Compliant with 21 CFR Part 11 audit trails, pharmacopoeia standards, and electronic signatures.
Supports network printing and data statistics retrieval.
Multi-level permission management with freely configurable permissions.
7-inch color touchscreen with a user-friendly interface.
The entire unit is TART and CE certified.
