Automatic Refractometer ADR5
Automatic Abbe refractometer can measure the mass fraction (Brix) of transparent, refractive index nD and translucent liquid sucrose solution, glucose, F42fructose syrup, and F55 fructose syrup, but also the solid content of juices, vegetables, honey water content, soft drinks and canned products and user-defined polynomial measurement units. It has a thermostatic control function, using a sapphire prism. The color touch screen is user-friendly. It can perform automatic measurement, with fast speed and good reproducibility. It has the temperature correction, USB, U disk storage and printing functions (the printer is optional). The instrument is compact, built with a variety of industry standard and user-defined measurement units.
The Refractive index is an important optical constant of a substance, which facilitate to understand the optical properties of a substance. The instrument can measure a variety of solution mass fraction (Brix) (0-95%, equivalent to the refractive index of 1.333-1.531).
Therefore instrument can be used in a wide range, including oil industry, oil and fat industry, pharmaceutical industry, paints industry, food industry, daily chemical industry,
sugar industry, geological survey and other relevant factories, schools and scientific research organizations.

Fully Automated, High-Precision Refractive Index Analysis: Automatic Refractometer ADR5
Achieve lab-grade concentration and purity measurements with minimal effort using the Automatic Refractometer ADR5—a smart, benchtop instrument engineered for pharmaceuticals, food & beverage, chemicals, and academic laboratories. Fully compliant with ISO 2173, OIML R133, and USP <831>, the ADR5 delivers ±0.00002 refractive index (nD) and ±0.01% Brix accuracy with one-click operation, automated temperature control, and seamless data management—ideal for QC, R&D, and regulated environments.
Engineered for Automation, Accuracy, and Compliance
The ADR5 Automatic Refractometer features a high-resolution optical sensor, Peltier temperature control (10–100°C ±0.01°C), and an automatic sample delivery system (via syringe or optional peristaltic pump) that minimizes user error and cross-contamination. Just place your sample—liquid, paste, or semi-solid—and the ADR5 measures, records, and cleans the prism automatically. Results are displayed instantly in nD, % Brix, HF, concentration (custom curves), or user-defined units.
- Ultra-High Accuracy: ±0.00002 nD / ±0.01% Brix – Suitable for pharmacopeial and R&D-grade analysis.
- Fully Automatic Operation – Auto-measurement, auto-cleaning (with solvent rinse), and auto-drying cycle.
- Peltier Temperature Control: 10–100°C (±0.01°C) – Ensures compliance with strict thermal standards.
- Large Touchscreen & Compliance-Ready Software – Stores 10,000+ results; supports 21 CFR Part 11, audit trails, and user roles.
- Multiple Sample Handling Options – Manual injection, autosampler (optional), or inline process probe (for continuous monitoring).
