Scigiene offers digital refractometers specially customized to measure %Brix, Potential Alcohol (% vol), %Brix, °Oechsle (°Oe) and °KMW (°Babo).  These are optical instruments that measure the refractive index of a solution. The measurement of refractive index is simple and quick and provides the vintner an accepted method for sugar content analysis.  Within seconds the instrument measures the refractive index of the grape. This digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements in the field.
