Specifications
The MA888 is an optical instrument that employs the meas-
urement of the refractive index to determine the % volume
and freezing point of ethylene glycol based coolants or
antifreeze.
The digital refractometer eliminates the uncertainty associat-
ed 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 measure-
ment 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
th
Edition).
The temperature (in °C or °F) is also displayed on
the large dual level display along with 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
