Possibly one of the Italian scientists of the period of Torricelli and Galileo who were involved with Weather instruments such as the now-obsolete columnar barometer still used metaphorically in fund raising events! The clever argument that Wassermann ( of VD blood test fame) invented the Hydrometer appears to be play on words ( Wassermann literally means Water Man) -but they do use the same scale- 4.l0 being the highest reading ( applies to battery hydrometers of the more modern type- and the Syphilis test. oh by the way it is 4.0 or 4 Plus.

The hydroscope (also called the hydrometer) is thought to be invented by Hypatia of Alexandria. If this is true, the first hydroscope was invented in the 4th century.
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
A hydrometer is used to find the specific gravity (or relative density) of liquids.

A thermohydrometer is actually a regular hydrometer that has a thermometer inside the float section. It is very similar to the regular hydrometer.
