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 MA886 is an optical instrument that employs the measurement of the refractive index
to determine sodium chloride concentration in aqueous solutions used in food preparation.
It is not intended for sea water salinity measurements. The measurement of refractive index
is simple and quick and provides the user an accepted method for NaCl analysis. Samples
are measured after a simple user calibration with deionized or distilled water. Within
seconds the instrument measures the refractive index of the solution. The digital refractometer
eliminates the uncertainty associated with mechanical refractometers and is easily portable
for measurements where you need them.

The instrument utilizes internationally recognized references for unit conversion and
temperature compensation. It can display the measurement of NaCl concentration 4 different
ways: g/100 g, g/100 mL, Specific Gravity, and °Baumé.

Temperature (in °C or °F) is displayed simultaneously with the measurement (on 3 of the
ranges) on the large dual level display along with icons for Low Power and other helpful
message codes.

Key features include:

• Waterproof models offers IP65 waterproof protection

• Automatic Temperature Compensation (ATC)

• Battery operation with Low Power indicator

• Automatically turns off after 3 minutes of non-use.
