RePo-1 Portable Refractometer + Polarimeter


Brix 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.


Announcing an All-in-One, refractometer and polarimeter hybrid unit. As little as 3mL sample, RePo-1 can measure both brix and optical rotation of the sample. With the press of a button, purity, international sugar scale, specific rotation, and concentration can be displayed. Users can also set an upper and lower measurement limit. An indicator light alerts the user if a measurement value is within the limits, allowing for optimal efficiency.


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