Published on Aug. 2, 2023, 9:13 p.m.

Thermal Imaging Technology Background

Thermal imaging technology is a non-destructive testing technique that generates images by detecting the infrared radiation emitted by objects. All objects emit infrared radiation, the intensity of which is related to the temperature of the object. Thermal imagers detect and record this infrared radiation, then convert it into visible images. Thermal imaging technology has wide applications in industries such as industrial, construction, medical, etc., used for detecting heat distribution in electrical equipment, diagnosing thermal leaks in building structures, monitoring temperature changes in medical patients, etc. With the continuous development of technology, thermal imaging technology has become an indispensable tool in many industries.

The PerfectPrime IR281 is an innovative handheld infrared thermal imager that allows users to see and measure temperatures across a wide range. With a high resolution thermal sensor and built-in visible light camera, this versatile tool has many applications for professionals and hobbyists alike.
