Example of hand held electric heat gun Commercial heat gun kit Flame heat gun for shrinkwrapping helicopter. A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 and 550 °C (373 and 823 K; 212 and 1,022 °F), with some hotter models running around 760 °C (1,030 K; 1,400 °F), which can be held by hand.
With the effectiveness of gun-fired single charge HEAT rounds being lessened, or even negated by increasingly sophisticated armoring techniques, a class of HEAT rounds termed high-explosive anti-tank multi-purpose, or HEAT-MP, has become more popular. These are HEAT rounds that are effective against older tanks and light armored vehicles but ...
A less commonly used thermal oxidizer technology is a thermal recuperative oxidizer. Thermal recuperative oxidizers have a primary and/or secondary heat exchanger within the system. A primary heat exchanger preheats the incoming dirty air by recuperating heat from the exiting clean air.
A sailor checking the temperature of a ventilation system. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or another controlled atmosphere; or in applications where a fast response is required, the accurate surface temperature is desired or ...
[3] In 2023, Exergen through Pompei emphasized the importance of this mission ahead of cold and flu season stating, "It is our responsibility to educate healthcare professionals and consumers that non-contact infrared thermometers (NCITs) are inaccurate, and on how to correctly take a temperature reading."

The compression of the air when the piston is quickly forced into the cylinder causes the interior temperature to rise sharply to over 400 °F (260 °C), the autoignition temperature of tinder. This is hot enough for the tinder in the piston face to ignite with a visible flash that can be seen, if the cylinder is made of translucent or ...
