American Heritage® Dictionary of the English Language, Fourth Edition
- n. Any of various thermometers used for measuring high temperatures.
Century Dictionary and Cyclopedia
- n. An instrument, in the form of simple metallic bar, employed by Muschenbroek, about 1730, for measuring the changes produced in the dimensions of solid bodies by the application of heat. ; ; ; ; ; ; ; ; . The name is now applied, however, to any instrument the object of which is to measure all gradations of temperature above those that can be indicated by the mercurial thermometer. Wedgwood's pyrometer, the first which came into extensive use, was employed by him for testing the heat of his pottery- and porcelain - kilns, and depended on the property of clay to contract on exposure to heat. Many different modes have been proposed or actually employed for measuring high temperatures: as by contraction, as in Wedgwood's
- n. A thermometer designed to measure high temperatures.
- n. An instrument for measuring the thermal expansion of solids.
GNU Webster's 1913
- n. (Physics) An instrument used for measuring the expansion of solid bodies by heat.
- n. (Physics) An instrument for measuring degrees of heat above those indicated by the mercurial thermometer.

“Pyrometer: A pyrometer is a sophisticated thermometer used to measure high temperaturesin brick kilns.”
“A somewhat similar instrument is the Gauntlett pyrometer, which is largely used in the north of England.”
“The electric pyrometer, which is perhaps the most elegant and original of all William Siemens's inventions, is also the link which connects his electrical with his metallurgical researches.”
“Experience-based strategies could establish the heat of the kiln during for and during firing, and tools such as Wedgwood's pyrometer added further control for the process. 41”
“Jerry spaced the burns and kept an eye on the pyrometer, adding just enough heat to make up for routine cooling inside the envelope.”
“In his other spare time Stanhope invented a printing press, a pyrometer, fireproofing (his demo involved burning the ground floor while interested parties ate ice cream on the upper floor, unscathed), a multiplying-and-dividing machine, and a floating mine (before Fulton).”
“If I were doing this, I would get the gadgets in the USA - blower, pyrometer, and any controls you wanted (if you want them).”
“But that it might act with regularity, the apparatus must be kept in perfect order; so each morning Michel visited the escape regulators, tried the taps, and regulated the heat of the gas by the pyrometer.”
“A pyrometer monitors the temperature, which can be controlled by shutting or opening the holes, maintaining a temperature around 650° C for 2 - 3 hours.”
“The wire leading from the thermocouple to the pyrometer is made from metals electrically similar to the ones used in the thermocouple and if ordinary wire is used the pyrometer will not be accurate.”
