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 MA888 is an optical instrument that employs the measurement of the refractive
index to determine the % volume and freezing point of ethylene glycol based coolants or
antifreeze. The digital refractometer eliminates the uncertainty associated with mechanical
refractometers and is easily portable for use in the field to optimize your cooling system.
The MA888 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 two measurement units; % Volume or Freezing Point. The instrument utilizes internationally recognized references for unit conversion and temperature compensation for ethylene glycol
solutions (e.g. CRC Handbook of Chemistry and Physics, 87
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.
