Who Invented Thermometer First?


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.

Who is the father of medical thermometer?

Daniel Gabriel Fahrenheit was a German physicist and a glassblower who dedicated his life to science and inventions. Fahrenheit was born on this day, May 24, in the year 1686. In 1714, Fahrenheit invented the modern mercury thermometer.

Who invented forehead thermometer?

Francesco Pompei of the Exergen Corporation introduced the world’s first temporal artery thermometer, A non-invasive temperature sensor which scans the forehead in about two seconds and provides a medically accurate body temperature.

Who invented thermometer answer?

The thermometer was invented by Galileo Galilei in 1593. The first to put a numerical scale on the thermoscopes was the Italian inventor Santorio Santorio for use in medicine. In 1593, Galileo Galilei invented a rudimentary water thermometer (using the contraction of air to draw water up a tube).

Is it illegal to have a mercury thermometer?

In 2001, California passed the California Mercury Reduction Act of 2001 (SB 633 – Sher). The law also prohibited the sale or supply of mercury fever thermometers after July 2002. Mercury thermostats were banned from sale in California in January 2006.

What was the first thermometer?

Thermoscopes were the earliest types of thermometers and they only showed changes in temperature but didn’t show numerical values. One of the first thermoscopes was developed by Italian inventor, Galeleo Galilei in 1593.It used water as the liquid and glass bulbs inside an open tube.

Which thermometer do doctors use?

Ford says doctors tend to rely on thermometers that read as close to the core body temperature as possible, noting that under-tongue thermometers tend to give the most accurate readings, and are used widely by doctors. However, Ford noted non-contact thermometers are also useful, especially during the pandemic.


What thermometer do hospitals use?

This is the infrared thermometer used by hospitals for its convenient and hygienic operation that provides an accurate temperature reading in only one second without touching the patient.

Who uses thermometer?

Thermometers measure temperatures in degrees, according to either the Celsius or Fahrenheit system. Meteorologists use thermometers to find out how hot it is or if it’s below freezing. Doctors use thermometers to check your body temperature — a very high or low body temperature means you’re sick.

Can you put a digital thermometer in your mouth?

A digital thermometer can be used three different ways. These include: Oral: For this method, the thermometer is placed under the tongue. This method is used for adults and children 4 and over who are able to hold thermometer in mouth.

What is the normal temperature of a healthy human?

Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).

What is a forehead thermometer made of?

Mercury-in-glass thermometers have been considered the most accurate liquid-filled types. However, mercury is a toxic heavy metal, and mercury has only been used in clinical thermometers if protected from breakage of the tube.

What is the basic principle of thermometer?

These liquid thermometers are based on the principal of thermal expansion. When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers.

Why is the thermometer important?

Thermometers are used to measure the temperature and this is a very important part of weather forecasting. Many thermometers come in a glass tube that contains a liquid, usually mercury or alcohol. Knowing the air temperature is very important. It is an important part of weather forecasting.
