Digital Refractometers for
Grape Juice Must Measurements
The MA882, MA883, MA884 and MA885 are optical instru-
ments that are based on the measurement of 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. Samples are measured
after a simple user calibration with deionized or distilled
water. Within seconds the instrument measures the refrac-
tive index of the grape. This digital refractometers eliminate
the uncertainty associated with mechanical refractome-
ters and are easily portable for measurements in the
field. The four instruments utilize internationally
recognized references for unit conversion and
temperature compensation.
• MA882 measures %Brix;
• MA883 measures °Baumé;
• MA884 measures %Brix and Potential
Alcohol (% vol);
• MA885 measures %Brix, °Oechsle
(°Oe) and °KMW (°Babo).
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.
Key features include:
• Dual-level LCD
• Automatic Temperature Compensation (ATC)
• Easy setup and storage
• Battery operation with Low Power indicator (BEPS)
• Automatically turns off after 3 minutes of non-use
