The Hanna Instruments-96816 digital wine refractometer is rugged, lightweight and water resistant for measurements in the lab or field.


This optical instrument employs the measurement of the refractive index to determine parameters pertinent to the wine industry.


The actual measurement of the refractive index is simple and quick and provides the vintner a standard accepted method for sugar content analysis. Samples are measured after a simple user calibration with deionised or distilled water. Within seconds, the instrument measures the refractive index of the grape must. These digital refractometers eliminate the uncertainty associated with mechanical refractometers and are ideal for fast, reliable measurements in the field.


Hanna Instruments-96816 converts the refractive index of the sample to sucrose concentration in units of percent by weight, %Brix (also referred to as °Brix). The conversion used is based on the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Since the majority of sugar in grape juice is fructose and glucose and not sucrose, the reading is sometimes referred to as "Apparent Brix".


The potential alcohol curve is based on the following equation:


potential alcohol (%v/v) = g/L of Sugar / 16.83.
