RePo-5 Portable Refractometer + Polarimeter


The RePo-5 can determine refractive index (nD).

In addition to angle of rotation and Brix, the RePo-5 can also display the refractive index (nD) of a sample. 
The RePo-5 is ideal for quality control in various industries such as fragrances, cosmetics, or pharmaceutical.


A fusion of refractive index and optical rotation - Making the invisible, visible-
