Infrared thermography is a non-contact, non-destructive testing technique that uses infrared cameras to detect and measure thermal energy emitted from an object. Every object at a temperature above absolute zero emits a certain level of infrared radiation, which this technology captures to visualise heat patterns, gradients, and points of excessive heat or cold. In industrial settings, these thermal images, or thermograms, are invaluable for identifying equipment anomalies that are invisible to the naked eye.
