Portable Refractometer Polarimeter

The Atago Portable Refractometer Polarimeter (RePo-1) measures the refractive index and angle of rotation simultaneously. With RePo-1 it is now possible to know the actual quantities of each dissolved solids in a measured solution such as fructose and glucose content. This is an ideal instrument for applications such as sugar  and honey industries, and in the analysis of inverted sugar syrups and fragrances.

RePo-1 is user-friendly and easy-to use. Simply fill the stage with approx. 3mL, press start, and the measurement is displayed. The Purity, International Sugar Scale, Specific Rotation, and Concentration are all automatically calculated, while the temperature is displayed constantly. The measurement evaluation indicator will easily notify the user when the measurement is within (green light) or outside of (red light) the pre-set tolerance.

Key Features

  • Measures refractive index and angle of rotation simultaneously
  • As little as 3mL of liquid sample
  • Evaluation indicator for pre-set tolerances
  • Measurement scales– Angle of Rotation, Brix (%), International Sugar Scale, Temperature (°C, °F)
