Modern digital thermometers all descend from the first medical thermometer invented by Sir Thomas Allbutt. For almost a hundred years thermometers were basically unchanged. It is non-invasive easy to use asleep or awake.

Santorio Santorio the first thermometer. The Italian Santorio Santorio 1561-1636 is generally credited with having applied a scale to an air thermoscope at least as early as 1612 and thus is thought to be the inventor of the thermometer as a temperature measuring device. The device is held either at the forehead or behind the earlobe and gives a reading in seconds.

This gives accurate readings and uses RATE technology. The first real medical thermometer was invented by Sir Thomas Allbut in 1867. The more modern thermometer was invented in 1709 by Daniel Fahrenheit.

The Celsius and Kelvin scales were invented later. The memory recalls previous temperature readings for comparison. The first electronic clinical thermometer invented in 1954 used a flexible probe that contained a Carboloy thermistor.

The early version of this thermometer contained alcohol and in 1714 Fahrenheit developed a mercury thermometer using the same scale. Thermometers were further evolved and converted to digital form. It was six inches long and took about five minutes to take a persons temperature.

This was invented in 1997. Digital thermometers have replaced mercury thermometers because mercury is toxic. English physician Sir Thomas Allbutt 18361925 invented the first practical medical thermometer used for taking the temperature of a person in 1867.

Digital thermometers are. The scale of the thermometer was debated until Daniel Fahrenheit developed the Fahrenheit scale nearly 100 years after the air thermometer was invented. More modern thermometers were developed after World.

As early as 220 BC Philo of Byzantium noted the expansion and contraction of air with hot and cold. When were thermometers invented. In 1612 the first crude clinical thermometer was invented by an Italian inventor Santorio Santorio.

Jacob Fraden at Advanced Monitors Corporation its CEO who created in 1984 what is now the most widely used of ear thermometers but that required digital thermometer technology. Resistance temperature detectors RTDs RTDs are wire windings or other thin film serpentines that exhibit changes in resistance with changes in temperature. 1686-1736 by Andres Celsius.

1612 Santorio Santorio The First Thermometer The Italian Santorio Santorio 1561-1636 is generally credited with having applied a scale to an air thermoscope at least as early as 1612 and thus is thought to be the inventor of the thermometer as a temperature measuring device. In 1593 an early water thermoscope was invented by Galileo Galilei.
