Jan 3, 2021 · Daniel Gabriel Fahrenheit was the German physicist who invented the alcohol thermometer in 1709 and the mercury thermometer in 1714. In 1724, he introduced the standard temperature scale that bears his name—Fahrenheit scale—that was used to record changes in temperature in an accurate fashion.
The earliest documented use of mercury in a thermometer stretches as far back to perhaps the 1620s when the Jesuit scholar, Athanasius Kircher, used quicksilver for his air thermometer, the precursor to in-glass thermometers.
He manufactured high-quality thermometers with mercury (which has a high coefficient of expansion) with an inscribed scale with greater reproducibility. It was this that led to their general adoption. Fahrenheit first calibrated his thermometer with ice and sea salt as zero.
Sep 1, 2023 · It was Fahrenheit who invented the mercury thermometer around 1714. This type could measure a wider range of temperatures compared to the alcohol thermometer. The 'air' inside the thermometer was another consideration that would improve accuracy and for this reason, the much more sensitive nitrogen or argon gasses came to be used inside the ...
Jun 1, 2021 · Eventually, his path crossed with Rømer’s in Amsterdam. Their collaboration spawned the first quicksilver (mercury) thermometer, which afforded greater accuracy and precision than its...
Daniel Gabriel Fahrenheit was a Polish-born Dutch physicist and maker of scientific instruments. He is best known for inventing the mercury thermometer (1714) and developing the Fahrenheit temperature scale (1724), which is still commonly used in the United States. Fahrenheit spent most of his life.
In the 1660s, Robert Hooke (1635-1707), at the Royal Society in London, attempted to construct thermometers that would universally agree at one fixed point: that at which distilled water started to freeze. He experimented with several thermometric liquids, such as spirit and mercury, to use inside his thermometers.
