Infrared thermography is the process of using a thermal imager to detect radiation (heat) coming from an object, converting it to temperature and displaying an image of the temperature distribution. Images of the detected temperature distribution are called thermograms, and they make it possible to see heat-producing objects invisible to the naked eye. It's widely-used in predictive maintenance and condition monitoring.
Objectives:
At the end of Level II course, participants will be able to:
- Understand temperature unites.
- Measure the temperature on any object
