Thermometer Apr 2026

The invention of the thermometer is widely credited to Italian mathematician and physicist Galileo Galilei around 1592, who created a crude water thermometer that measured temperature changes through the expansion or contraction of air. This early instrument was also sensitive to air pressure, making it part-barometer.

Infrared thermometers calculate temperature by measuring the thermal radiation emitted by an object. These are commonly used for rapid surface or forehead measurements, as they do not require contact with the object being measured. Common Types of Thermometers thermometer

Used to detect and monitor body temperatures, helping to assess for fever or hypothermia. These are commonly used for rapid surface or

Common for environmental or laboratory use, these are rarely used in medical settings today due to the risks associated with broken glass and toxic liquids. Key Uses and Applications Thermometers are crucial in numerous fields:
