Thermometer

A thermometer is a device that measures temperature or a temperature gradient using a variety of different principles. A thermometer has two important elements: the temperature sensor (e.g. the bulb on a mercury-in-glass thermometer) in which some physical change occurs with temperature, plus some means of converting this physical change into a nu...

Thermometer

A thermometer is a device used to measure temperature. It was invented by Galileo in 1592. The graduation and inclusion of fixed points was added by Sanctorio who used snow and the heat of a candle, dividing the range obtained into degrees. The first sealed thermometer was made by Ferdinand II, the Grand Duke of Tuscany, in 1654. He filled the bulb...
