The handheld Fluke 68 infrared thermometer provides non-contact infrared temperature measurement. Non-contact Fluke 68 infrared thermometers are the professional diagnostic tool for HVAC technicians performing room balance checks, electricians evaluating electrical connections, and auto mechanics diagnosing catalytic converters.

Portable Fluke 68 infrared thermometers enable professionals to research heating and ventilation problems, monitor the status of electrical motors and electrical panels, and diagnose car malfunctions with ease. The Fluke 68 infrared thermometer measures surface temperatures, helping to quickly locate potential blockages or malfunctioning systems reducing work time and improving performance.

The Fluke 68 infrared thermometer's laser sighting system guides measurements to the right target and indicates the approximate center of the measurement area. With a distance to spot ratio of 50:1, use your non-contact Fluke 68 infrared thermometer within 25 feet (8 meters) of the intended target. At greater distances, the Fluke 68 infrared thermometer's measured area will be larger (approximately the distance divided by 50).

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.
