GENERAL DESCRIPTION

SIGNIFICANCE OF USE

Thank you for choosing Milwaukee. This instruction manual will provide you the
necessary information for correct use of the meter.

The MA882, MA883, MA884 and MA885 are optical instruments 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 refractive index of the grape. This digital
refractometers eliminate the uncertainty associated with mechanical refractometers 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

Potential Alcohol (% vol)

MA885 measures %Brix

°Oechsle (°Oe)
°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

• Automatically turns off after 3 minutes of non-use

• Single-point calibration with distilled or deionized water

• Waterproof models offers IP65 waterproof protection

• Quick, precise results readings are displayed in approximately 1.5 seconds

• Small sample size as small as 2 metric drops.
