The Galileo thermometer is a decorative instrument that measures ambient temperature, and unlike the Fitzroy storm glass—it is reasonably accurate. We think it’s an excellent option for those looking for a unique gift for a weather enthusiast.
Simply so, are glass thermometers accurate?
The accuracy of a typical glass thermometer is ±1 scale division. These are available in partial immersion or total immersion types and typically have to be considerably longer to achieve the same specifications as a mercury thermometer.
Also to know is, how do you read a floating glass thermometer?
To read the ambient temperature on a Galileo thermometer is very easy. What you have to do is simply look at the lowest ball that is floating while ignoring those tags that had sunk to the bottom of the container. It’s those balls that float or are neutrally buoyant that interest us.
How do you refill a Galileo thermometer?
Insert the tube into the storm glass until it reaches the bottom of the bulb. 4. Slowly pump the liquid out until all of the liquid is gone. The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles.
How does Galileo glass thermometer work?
Galileo thermometers work on the principle of buoyancy, which determines whether objects float or sink. As the temperature changes, the glass balls will either sink to the bottom (temperature rises), or float to the top (temperature falls).

What is the largest Galileo thermometer?
Contains 10 weighted balls that rise or fall according to temperature.
What oil is in Galileo thermometer?
The liquid in a Galileo thermometer is water. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used. The Galileo thermometer is an accurately functioning machine that is more often than not used today as decoration.
