Infrared Temperature Measurement - Technology Explained:

Infrared thermometers measure temperature from a distance by detecting the amount of thermal electromagnetic radiation emitted from the object being measured. This allows users to accurately measure surface temperatures in hazardous or hard-to-reach places, or other situations in which non-contact temperature measurement is desirable. Infrared thermometer technology is useful in a wide range of applications – including industrial, laboratory, food service, fire fighting, hobby, and home use.

While the technology is relatively simple, the myriad of names given to these devices can be confusing. "Laser Thermometers" makes reference to the laser that helps aim the thermometer. "IR Sensors" and "IR Thermometers" make use of a common abbreviation for "infrared". "Non-Contact Thermometers" is descriptive of the device's ability to measure temperature from a distance. "Radiation Pyrometers" is a scientific/technical term for these devices.
