Temperature Range: 19-25˚C in 1˚C increments

Galileo Galilei (1564-1642) was an Italian scientific genius who founded modern physics with his reliance on experience and experiment. Among countless discoveries of natural laws he succeeded in developing a thermometer based on the law of physics which states that the specific gravity of liquids changes as they expand at different temperatures.

Functional principle: All liquids change their specific gravity as a result of changes in temperature. This principle has been used in the Galilei thermometers. As the temperature rises the liquid expands. Its specific gravity decreases and the spheres sink. The current temperature is indicated by the lowest of the spheres which are still floating. To achieve an accuracy of ½ °C the glass spheres have to be precisely weighted to within two thousandths of a gram.

The manufacturer Dr Friedrichs Gruppe uses none other than the highest-grade materials when producing Galileo thermometers. Stainless steel is used for all metal parts and the glass is Duran glass made by Schott.
