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 MA887 is an optical instrument that employs the measurement of the refractive index
to determine the salinity of natural and artificial seawater, ocean water or brackish intermediates. The digital refractometer eliminates the uncertainty associated with mechanical
refractometers and is easily portable for ship, shore or home use.
The MA887 refractometer is an optical device that is simple and quick to use. Samples are
measured after a simple user calibration with distilled or deionized water. Within seconds,
the refractive index and temperature are measured and converted into one of three popular
measurement units; Practical Salinity Units (PSU), Salinity in parts per thousand (ppt), or
Specific Gravity (S.G. (20/20)). All conversion algorithms are based upon respected
scientific publications using the physical properties of seawater (not sodium chloride). The
temperature (in °C or °F) is also displayed on the large dual level display along with 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.
