The Milwaukee MA872 Digital Refractometer for Fructose Measurements, 0 to 85% mass, 0 to 80°C (32 to 176°F is an optical instrument that employs the measurement of refractive index to determine the % Fructose in aqueous solutions. The method is both simple and quick. Samples from expressed, reconstituted or concentrated juice are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the sample and converts it to % by weight concentration units.

The MA872 digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements in the plant. The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (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.
