ABSTRACT:
A combined hydrometer for measuring the specific gravity of a radiator fluid and a battery fluid including a fluid chamber having a transparent front window, a substantially horizontal axis in the chamber, an upper battery fluid scale having readings corresponding to the specific gravity of a battery fluid and a lower calibrated scale having readings corresponding to the freezing temperature of a radiator fluid. An indicator float and a second float are mounted eccentrically in the fluid chamber for pivotal movement about the axis, the indicator float having a relatively smaller specific gravity than the second float and being mounted on the axis between the second float and the front window. The indicator float normally rests with a tip end therof facing a lowermost point on the radiator fluid scale and the second float normally rests with a tip end thereof facing a lowermost point on the battery fluid scale. A projection extending from the indicator float towards the second float carries the second float along with the indicator float when the indicator float is angularly deflected beyond the resting position of the second float. The combined hydrometer permits measurement of the freezing temperature of a radiator fluid when the fluid chamber is filled with a radiator fluid and also allows measurement of the specific gravity of a battery fluid when the fluid chamber is filled with a battery fluid.
