Digital mini benchtop refractometers


The MA885 measures the density of grape juice in the °Brix, °Oechsle and °KMW units. The MA885 function is based on measurement of the refractive index of a solution. Measurement of the refractive index is both simple and speedy. It provides the vintner with an accepted method for recording the sugar content of grape juice. Calibration is realised easily with deionised or distilled water. In addition to eliminating measurement uncertainties that are peculiar to optical refractometers, the digital refractometer is also light and easy to transport, making it suitable for use in the field. The device uses internationally recognised unit conversions and compensates for temperature during operation. In addition to a battery status indicator and other helpful symbols, the temperature is simultaneously shown as a measurement value on the display.
