The fluid analyzer is used to analyze the boiling point of brake fluid or radiator fluid. The analyzer used the reflux boiling point to measure boiling point temperature. The boiling point has a direct correlation to the amount of moisture in brake fluid and the percent glycol in the radiator fluid. The unit is a self-cleansing, reproducible sample introduction, and is simple to operate. The Analyzer is controlled by a PC, has an alphanumeric display, keypad, and dot-matrix printer.
