Infrared thermography is a non-invasive imaging technique that detects and measures heat emitted from objects. It uses infrared cameras to capture thermal images, allowing users to visualize temperature differences on surfaces. This technology is commonly used in various fields, including building inspections, electrical maintenance, and medical diagnostics. By identifying temperature variations, infrared thermography can help locate issues such as insulation gaps, electrical faults, or inflammation in tissues. The images produced provide valuable information for preventive maintenance and troubleshooting, making it an essential tool for professionals in many industries.
