The first thermometers were called thermoscopes, and Italian inventor Santorio Santorio was the first person to put a numerical scale on the instrument.

Galileo Galilei invented a rudimentary water thermometer in 1593, which for the first time, allowed temperature variations to be measured. In 1714, Gabriel Fahrenheit invented the first mercury thermometer, the modern thermometer.

Thermometer & Clock in One

In a mercury thermometer, the liquid expands as it is heated and contracts when it is cooled, so the length of the liquid column is longer or shorter, depending on the temperature.
