Pyrometer \Py*rom"e*ter\, n. [Pyro- + -meter: cf. F. pyrom[`e]tre.]
(Physics) An instrument used for measuring the expansion of solid bodies by heat.
-
(Physics) An instrument for measuring degrees of heat above those indicated by the mercurial thermometer.
Note: It is usually constructed so as to register the change which the heat to be measured produces in the length of some expansible substance, as a metallic rod, or in the intensity of a thermo-electric current.
Wiktionary

A pyrometer is a type of remote-sensing thermometer used to measure the temperature of a surface. Various forms of pyrometers have historically existed. In the modern usage, it is a device that from a distance determines the temperature of a surface from the spectrum of the thermal radiation it emits, a process known as pyrometry and sometimes radiometry.
The word pyrometer comes from the Greek word for fire, "πυρ" (pyro), and meter, meaning to measure. The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. Modern pyrometers or infrared thermometers also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux.
Usage examples of "pyrometer".
He checked the rigging and equipment, the altimeter, charts, a pyrometer to monitor the temperature of the envelope, a rate of climb indicator, and a tool kit.
The pyrometers used at present are the Wanner optical pyrometer and the Fery radiation pyrometer.
Joya showed me the small instrument panel and explained it to me: variometer for rate of ascent and descent, pyrometer for temperature up in the crown of the balloon, compass-which she said was not very meaningful because there was no way to steer once you were aloft.
Dave disconnected the pyrometer, and we packed the envelope in the bag, inspecting it as it was accordion-folded in.
As the men were hooking the load cables to the tie blocks, Joya showed me the small instrument panel and explained it to me: variometer for rate of ascent and descent, pyrometer for temperature up in the crown of the balloon, compass-which she said was not very meaningful because there was no way to steer once you were aloft.
Staring through the blue glass peephole at the six piles of glowing dust, waiting for them to shimmer, coalesce, and run into liquid, was hypnotically soothingexcept that he could sense Lilly at his side, with her eyes on the thermocouple pyrometer and her full hips near him, giving him thoughts that he found alarming.
Lilly at his side, with her eyes on the thermocouple pyrometer and her full hips near him, giving him thoughts that he found alarming.

Dogran squinted again at the pyrometer, to see that the temperature was still falling, grudgingly.
Ken followed the suggestion, testing first the sound apparatus and then the various recorders and other instruments in the cargo chamber which were intended to tell whether or not any violent chemical reactions took place photocells and pyrometers, and gas pumps connected to sample flasks and precipitators.
The temperature was almost unaffectedif anything, it dropped more slowly, for the recording pyrometers were now insulated by a vacuum and the expansion of the gaseous sulfur into empty space had had no cooling effect to speak of.
