Infrared thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Thermographic camerasusually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 µm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one’s environment with or without visible illumination.
Thermal imagers from Testo are characterised by innovative technologies and practical features as well as by their excellent thermal image quality. So, thermal processes can for instance be ...
