34cm Galileo thermometers and black-wood-surround Galileo thermometers were invented to measure the air temperature. They are quite different from the other accustomed thermometers. That’s why their shapes and designs are distinct and unique. They are made up of big sealed glass tube (cylinder) with air bubbles blown upwards to the surface of the liquid filled within a glass.

As we all know that thermometer is a device which is used to check the temperature precision. And temperature does not always mean that it has to be body temperature. So the question arises what a Galileo thermometer is? In the past, no assumptions could be made about the heat and temperature on blazingly hot days until Galileo Galilee the very famous physicist invented this thermometer. And so the thermometer still bears his name. Galileo thermometers work on the principle that the density of a liquid changes as temperatures change. Each internal globe is exactly weighted to rise or fall as the temperature changes and thus can be used to accurately tell the temperature. Galileo thermometers come in many varieties but the 34cm Galileo thermometers and black-wood-surround Galileo thermometers are the best variations.
There are beautiful 34cm Galileo thermometers with multicolor balls. There are five to seven balls. The procedure of reading the temperature is easy and very interesting. How to read the 34cm Galileo thermometers and black-wood-surround Galileo thermometers? When there is a fluctuation in degrees of temperature, the movement of the balls in the device is disturbed. Means the balls with lower density rise above and the balls which are of higher density get drowned.
The reading of the temperature is done with attaching a tag to the lowest floating ball of the thermometer, which indicates the current temperature. The tags on the balls actually define the weights of the balls. When the balls have settled underneath that means the tube is hot and when the balls are on the surface of the liquid in the tube that means the tube is too cold. Glass 34cm Galileo thermometers are more accurate though plastic 34cm Galileo thermometers are also available. The light-weighted balls float upwards to the surface of the cylinder or glass tube where as the heavy-weighted balls sink to the bottom of the tube.
Black-wood-surround Galileo thermometers are unique looking thermometers. The black wood finish that surrounds the thermometer is beautifully crafted. It sits at 30cm including the Black ash wood finish. It has five multi-colored globes contained inside the temperature readings ranging from 18C to 26C. While was searching for a way to measure temperature accurately, Galileo Galilee discovered this fascinating method. He placed several glass globes filled with a certain liquid within a glass cylinder filled with another liquid.
