A hydrometer scale calibrated so that readings are the percentage of ethanol (ethyl alcohol) by volume. Zero on the scale is the level to which the instrument sinks in pure water at 60°F, and 100 is the level to which it sinks in pure ethanol at 60°F. It was used in Germany and in the U.S. Customs Service.
