A Thermal Imager is an instrument that detects infrared radiation and converts it into a visual thermal image, allowing temperature distribution to be monitored across surfaces. The main types include handheld thermal cameras (portable for field inspections), fixed-mount thermal cameras (for continuous process monitoring), and drone-mounted thermal cameras (for remote or large-area inspections). Thermal imagers are widely used in industries such as electrical maintenance, manufacturing, HVAC, and petrochemical plants to detect hotspots, prevent equipment failure, monitor process temperatures, and improve safety and energy efficiency.
