Bits and Pieces Galileo Thermometer

The temperature is indicated by the lowest floating sphere in the upper group. Each sphere has a metal tag with a specific temperature; if a sphere is floating in the middle, the temperature is between the values of the spheres above and below it.

No, this thermometer is designed exclusively for indoor use. Exposure to direct sunlight or extreme temperature fluctuations outdoors can damage the glass or affect the accuracy of the liquid density mechanism.

This model is calibrated to measure temperatures between 64ºF and 80ºF. It is best suited for monitoring standard room temperatures rather than extreme heat or cold.

It is crafted from borosilicate glass, which is durable but still breakable. Handle it with care when moving it, and place it on a stable, flat surface like a desk or shelf to prevent it from tipping over.

Galileo thermometers are primarily decorative instruments that provide an approximate temperature reading. While they are scientifically sound, they are not as precise as digital sensors and should be viewed as a classic, analog way to track general temperature changes.
