Digital refractometer BK-R30

for the food industrylaboratoryfor the pharmaceutical industry

Introduction
The BK-R30 automatic refractometer measures refractive index (nD) and Brix (mass fraction) for transparent, translucent, dark and viscous liquids. It is equipped with line-array CCD photosensitive sensors, fast signal acquisition and analysis, and a semiconductor Peltier temperature control system for controlled-measurement workflows.

Key features

• Peltier temperature control (5–70°C) with ±0.02°C control accuracy.
• Line-array CCD sensor and LED cold light source.
• 7-inch color touchscreen for on-site operation and result review.
• Data storage 32G and multiple interfaces: USB, RS232, RJ45, SD card, U disk.
• Functions supporting pharmacopoeia/FDA workflows and compliance with Chinese Pharmacopoeia (0622, 2020).
