Benchtop Digital Refractometer NBDR-201

Benchtop Digital Refractometer NBDR-201 can measure refractive indices of liquids within the range of 1.30000 to 1.70000 (nD). Its built-in Peltier temperature control system provides precise temperature regulation from 5℃ to 65℃. Capable of measuring the mass fraction of sugar solution (Brix) across a range of 0 to 100%. Utilizes high-resolution linear CCD photosensitive components for precise detection of refractive indices. Our refractometer is Enhanced with a 7-inch FTF color touchscreen display for easy operation.
