Introduction: Your portable refractometer is a
precision optical instrument designed to measure
the concentration of sugar in aqueous solutions.
It utilized the standardized Brix scale which is ac­curate and easy to read. The unit’s lightweight,
ergonomic design makes it convenient for both
laboratory and field applications. It is excellent
for quality assurance, process control require­ments, and scientific research.

The refractometer operates on the principle that
as the concentration or density of a solution in­creases, its refractive index changes proportion­ately. The refractive angle measured by your re­fractometer registers on the scale. The larger the
concentration of sugar in solution, the higher the
reading on the scale.
