Abstract
In order to determine the boiling point of a liquid, especially a nonaqueous one such as a brake fluid, a device suspended in a body of that liquid--e.g. in a reservoir supplying fluid to a brake cylinder--forms a narrow chamber which is open at the bottom and the top and which contains means for heating the liquid in that chamber and measuring its temperature; the two functions can be simultaneously performed by a thermistor. When the boiling point is reached and the liquid in the chamber is vaporized, partial evaporation of that liquid and replacement thereof by fresh liquid from the main body results in a leveling of the temperature curve; the boiling point marked by this event can be read on a meter and/or qualitatively indicated by differently colored lights, for example. An excessive temperature rise early in the test will also show an unduly low liquid level in the reservoir.
