A thermographic machine, also known as a thermal imaging camera, is a device that uses infrared technology to capture and display thermal images. These images are used to identify temperature variations across an object or scene, which can be used for a variety of applications such as industrial process control, building energy audits, and predictive maintenance in industrial setting. Thermographic machines are commonly used in industrial, commercial, and residential settings to detect and diagnose problems such as electrical issues, air leaks, and insulation deficiencies. They can also be used in the field of non-destructive testing, such as to detect cracks or other defects in structures and mechanical components, and in the medical field to detect disease. They are also used in the field of security and surveillance to detect human presence and movements in dark or low visibility conditions.
