Which of the following thermometers measures temperature from the thermal radiation emitted by objects?
-
Pyrometer thermometer
- Platinum resistance thermometer
- Thermocouple thermometer
- Constant pressure gas thermometer
The correct answer is: A
Explanation
A pyrometer is a type of remote-sensing thermometer used to measure the temperature of a surface. It does this by measuring the thermal radiation or infrared energy being emitted from the object. Therefore, a pyrometer thermometer measures temperature from the thermal radiation emitted by objects.
