What were the first thermometers made of?
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. The glass bulbs rose and fell with the changes in temperature.
How was the first mercury thermometer made?
In 1724, a German instrument maker called Gabriel Fahrenheit settled on mercury as the most suitable liquid for measuring temperature. He calibrated his first thermometer using a mixture of ice and water with sea salt as his zero.
Do thermometers still have mercury?
Although many people commonly associate thermometers with a mercury filling, the dangerous properties of mercury have spurred manufacturers to use other liquids inside the glass gauges. Some thermometers may still contain mercury but many typically contain less toxic liquids.
How was temperature discovered?
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. At the start of the seventeenth century there was no way to quantify heat.

What is the red stuff in a thermometer?
Mercury is a silver-white to gray substance. If your thermometer is filled with a red liquid, your thermometer contains red dyed alcohol or mineral spirits and not mercury.
What came first Celsius or Fahrenheit?
He originally had the scale in the opposite order of the scale used today — 0°C was the boiling point of water, and 100°C was the freezing point — but other scientists later reversed the scale. The Fahrenheit scale was first proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit.
Who invented centigrade?
Anders Celsius
Anders Celsius, (born November 27, 1701, Uppsala, Sweden—died April 25, 1744, Uppsala), astronomer who invented the Celsius temperature scale (often called the centigrade scale).
What was the first type of thermometer made?
It was an enclosed glass tube that had a numerical scale, called the Fahrenheit scale. The early version of this thermometer contained alcohol and in 1714 Fahrenheit developed a mercury thermometer using the same scale.
When did Thomas Allbut invent the first thermometer?
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.
What did Daniel Gabriel Fahrenheit invent the thermometer?
Daniel Gabriel Fahrenheit, the originator of the era of precision thermometry. He invented the mercury-in-glass thermometer (first widely used, accurate, practical thermometer) and Fahrenheit scale (first standardized temperature scale to be widely used). A medical mercury-in-glass maximum thermometer.
Who was the inventor of the Mercury in glass thermometer?
