Who invented mercury thermometer

His instrument therefore, should rightly be called a thermoscope. The predecessor to the thermometer — the thermoscope — is a thermometer without a scale; it indicates differences in temperature only i. The thermoscope was widely used by a group of scientists in Venice that included Galileo. It was then only a small step from the thermoscope to the creation of the thermometer.

The Italian, Santorio Santorio is generally credited with having applied a scale to an air thermoscope at least as early as and thus is thought to be the inventor of the thermometer as a temperature measuring device. Its accuracy was poor as the effects of varying air pressure on the thermometer were not understood at that time.

The sealed liquid-in-glass thermometer , more familiar to us today, was first produced in by the Grand Duke of Tuscany, Ferdinand II His thermometer had an alcohol filling. Although this was a significant development, his thermometer was inaccurate and there was no standardised scale in use.

Gabriel Fahrenheit was the first person to make a thermometer using mercury. The more predictable expansion of mercury combined with improved glass working techniques led to a much more accurate thermometer. Fahrenheit used the newly discovered fixed points to devise the first standard temperature scale for his thermometer.
