The Source Galileo Thermometer – the Galileo Thermometer

Description

In his quest for accurate temperature measurement, the ingenious Galileo Galilei discovered this impressive method.

Within a liquid, a solid body of the same weight and size necessarily descends as the temperature rises.

Conversely, the solid body rises in the liquid when the temperature decreases.

The glass balls have different weights. Taking into account the density of the liquid, it is guaranteed that the lowest of the balls floating at the top of the cylinder indicates the correct temperature.

The production of this instrument is particularly complex. Each ball is calibrated to exactly half a degree Celsius. The weight difference between two glass balls is only 6/100 of a gram.

The liquid in the cylinder does not contain CF2 gases, is almost non-flammable, is non-toxic, and does not cause any evaporation or gas hazardous to health.
