A medical mercury-in-glass maximum thermometer showing the temperature of 38.7 °C (101.7 °F). One special kind of mercury-in-glass thermometer, called a maximum thermometer, works by having a constriction in the neck close to the bulb. As the temperature rises, the mercury is pushed up through the constriction by the force of expansion.
1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible (i.e. two would give the same temperature) 1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the ...
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...
The first sealed thermometer was constructed in 1654 by the Grand Duke of Tuscany, Ferdinand II. [1]: 19 The development of today's thermometers and temperature scales began in the early 18th century, when Daniel Gabriel Fahrenheit produced a mercury thermometer and scale, both developed by Ole Christensen Rømer.
It is simultaneously dynamically connected to an external pressure reservoir, from which it is materially and thermally insulated. Other thermometers (e.g. mercury thermometers, which display the volume of mercury to the observer), may now be constructed, and calibrated against the ideal gas thermometer.
"I compared the thermometer with two others for the first time to compare for accuracy. This one is as accurate as any other I have used. Notably, 80% of all ovens I test are more than 20 degrees ...
Instant-read thermometers provide quick, accurate readings, probe thermometers are best for oven-roasting, digital thermometers offer precise results and alarms, and traditional dial thermometers ...
Fahrenheit invented thermometers accurate and consistent enough to allow the comparison of temperature measurements between different observers using different instruments. [2] Fahrenheit is also credited with inventing mercury-in-glass thermometers more accurate and superior to spirit-filled thermometers at the time.
