INTRODUCATIONJIE 介绍
Galileo thermometer
Manufactured after the idea of Galileo Galilei
(1564-1642)
History
Searching for exact temperature measurments,
Galileo Galilei discovered this fascinating method.
Galilei put 4-5 exactly weightedballs in a cylider filled with a special liquid.The balls go up or down according to the existing temperature.By this method you can determine the correct temperture.
Temperture indication
In liquid, a solid body with the same weight and size
is compelled to go down as temperture rises.On the
other hand the solid body goes up in the liquid if the
temperture falls.The glass balls differ in weight and
considering density of the liquid you are guaranteed
that the lowest of the floating balls in the upper part
of the cylinder indicates the temperature.
Measuring range:10-32℃(50-90℉)
Graduation:2℃(4℉)
