A Celsius Galilean thermometer in two degree gradations. A risen orange orb denotes 24 °C. A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the ...
Vapour pressure thermometer Density Galileo thermometer [45] Thermochromism Some compounds exhibit thermochromism at distinct temperature changes. Thus by tuning the phase transition temperatures for a series of substances the temperature can be quantified in discrete increments, a form of digitization. This is the basis for a liquid crystal ...

The Galileo Project, "The Thermometer" Benedict, Robert P., 1984. Chapter 1, "Early attempts to measure degrees of heat", in Fundamentals of Temperature, Pressure and Flow Measurement , 3rd ed, Wiley ISBN 0-471-89383-8 .
The Galileo Thermometer actually measures pressure in the first instance, the pressure being caused by the change in ambient temperature. The AIR in the top of the sealed container is heated by the outside temperature and it expands, applying pressure to the surface of the liquid, which is incompressible.
