In his search for the precise measurement of temperature, the genius Galileo Galilei discovered this impressive method.

Inside a liquid, a solid body, with the same weight and size, necessarily sinks as the temperature rises.

On the contrary, the solid body rises to 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 extremely complex. Each ball is calibrated to exactly half a degree Celsius. The difference in weight between two glass balls is only 6/100 of a gram.

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