Portable Refracto-Polarimeter RePo-2
The RePo-2 can determine the amount of fructose (%) in HFCS.
  • Like the RePo-1, the RePo-2 is a two-in-one refractometer and polarimeter hybrid.
  • In addition to angle of rotation and Brix, the RePo-2 also converts and displays the amount of fructose (%) within HFCS. 
  • The RePo-2 is ideal for various industries such as food and beverage, or sugar refining.

(*1) These ranges are measured by the device’s 20mm light path.
These are convertible to below ranges:
-25.00° to +25.00° with a 100mm observation tube
-50.00° to +50.00° with a 200mm observation tube
Any sample that has Angle of Rotation within above ranges can be measured by RePo units

Four Points

  1. 2 in 1
    Brix alone can only indicate the overall amount of dissolved solids in a solution. With REPO-1, it is possible to determine if a product has been adulterated by measuring the optical rotation. For example, fructose rotates light to the left while glucose rotates light to the right. If a sample has been adulterated with glucose, it will make the optical rotation readings appear more positive than a pure solution. 

  2. Compact size
    Great portability, 10.1×16.0×3.8cm and weighs only 325g.

  3. Automatically calculated scales
    Press ''User'' to select the desired scale: Purity, International Sugar Scale, Specific Rotation, and Concentration.

  4. Measurement evaluation indicator
    Measurements are evaluated against pre-set tolerance limits, and the result is indicated by green or red light. (Upper and lower tolerance limits must be set in advance to using this function)

Application Examples

Sugar industries

(sugar manufactures and refineries)
Analyzing inverted sugar syrups Analyzing fragrances
Honey industries
  • Investigating how fast different honey crystallizes by determining the fructose and glucose content

  • Researching honey collected from the same district, or honey collected from the same flower
Measuring Method

1. Fill the sample stage up to the fill line (approx. 3mL).
2. Press START.
3. Measurement is displayed.
