The digital refractometers are optical instruments that employ the measurement of refractive index to determine the % Brix of sugar (VT871), % Fructose (VT872), % Glucose (VT873) and % Invert Sugar (VT881) in aqueous solutions. The method is both simple and quick. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instruments measure the refractive index of the sample and convert it to % Brix or % by weight concentration units. The digital refractometers eliminate the uncertainity associated with mechanical refractometers and are easily portable for measurements in the field.

A refractometer measures the index of refraction for a material, which could be a gas, a liquid or a transparent solid such as glass. They achieve this by passing light through the sample and measuring the refraction — the amount that the light bends.

The digital refractometers eliminate the uncertainity associated with mechanical refractometers and are easily portable for measurements in the field. The measurement technique and temperature compensation employ methodology recommended in the (Internationally recognized body for Sugar Analysis). Temperature (in °C or °F) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.
