The first real medical thermometer was invented by Sir Thomas Allbut in 1867. It was six inches long and took about five minutes to take a person’s temperature.
For almost a hundred years thermometers were basically unchanged. They contained alcohol or mercury and were considered to be very accurate. More modern thermometers were developed after World War II that used infrared technology and placed in the ear.
They utilized tiny electrical circuits and numerical readouts that could measure temperature more quickly and with more precision than the liquid-filled glass tubes.
Today modern thermometers use some type of electrical sensors to measure temperature but the same numerical scales developed in the 1700s by Fahrenheit and Celsius are still being used.
Medical Grade Thermometer
As people plan to get back into a rut, many are considering buying technologies that can detect elevated temperatures. While it is not guaranteed that it can be determined if someone has an infection, temperature detection has its benefits.
