Refractive index (RI) measurements with the Abbemat automatic digital refactometer are fast and non-destructive. In refractometry, only a small volume of sample is required. For routine applications choose from different flow-through cells to suit your analysis and get RI and RI-derived results in seconds, e.g. the sugar content of a sample

Features

Attractive optical design

- High resolution of 0.000001 nD

- Measuring range from 1.32 to 1.56 nD (HP model) and in a wide range from 1.30 to 1.72 nD (WR model)

- The HP model is used for routine applications and also frequently as a sugar refractometer (ICUMSA)

- The WR model allows RI measurements of organic solvents, perfumes and aromas

Save space and money with internal temperature control

- Very fast adjustment of sample temperature

- No external thermocirculator required

- Internal Peltier thermostat adjusts the temperature accurate to ±0.03 °C

- Temperature control from 10 to 70 °C, optionally up to 110 °C (HPHT and WRHT model)

- Stability of the temperature adjustment is ±0.002 °C

Intuitive operation

- Easy operation combined with best performance by using a PC as an intelligent terminal

- Large number of pre-programmed scales

- Easy calibration

- GLP-conform data recording

- User management

- Wide range of measuring modes
