There is an ear thermometer?

The infra-red laser thermometer was invented by David Phillips in 1984. It was an ear thermometer. The original discovery of infra-red technology was in 1800 by William Herschel.
In 1714, Gabriel Fahrenheit invented the first mercury thermometer.
Santorio Santorio was the first inventor 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.
Galileo was the first one to invent the thermometer but another guy made a better thermometer than Galileo butt basically it is Galileo who invented the thermometer
An ear thermometer should be placed carefully in an ear to measure the temperature. The temperature is then taken by an infrared mechanism in the thermometer.
The first modern thermometer, the mercury thermometer with a standardized scale, was invented by Daniel Gabriel Fahrenheit in 1714.
