Galileo Thermometers
While Galileo was searching for exact temperature measurements he discovered this fascinating method that by putting four to five precision weighted balls in a cylinder filled with a special liquid, the balls go up or down according to the temperature.
In liquid, a solid body with the same weight and size is compelled to go down as the temperature rises. On the other hand the solid body goes up in the liquid if the temperature falls. The glass balls differ in weight and considering the density of the liquid you are guaranteed that the lowest of the floating balls in the upper part of the cylinder indicates the right temperature.
The production of this thermometer is extremely complicated and possible only by hand crafting. Each ball is blown and calibrated to exactly 2/10 oC. Two glass balls differ in weight by only six thousands of a gram. Due to the precise workmanship, the measurement accuracy is to within 2oC.
The liquid in the cylinder of these galileo thermometers is free of CFC gases, almost non inflammable and neither poisonous nor does it give off any vapour or gas that may injure health.
