Introduction to Thermal Imager
A thermal imager, also known as a thermal camera, is a device that uses infrared radiation to create a visible image based on the differences in temperature of objects in a scene. By detecting the infrared energy emitted by all objects with a temperature above absolute zero, thermal imagers can convert this energy into an electronic signal, which is then processed to produce a thermal image. The colors or shades in the thermal image represent different temperature ranges, allowing users to identify hot spots, detect hidden problems, and monitor temperature variations in various applications. Thermal Imager

Thermal imagers find wide – ranging applications across multiple industries. In the building industry, they are used for energy audits to identify areas of heat loss in buildings. In the field of security and surveillance, they can detect intruders in complete darkness. In electrical maintenance, they help locate overheating components in electrical systems. In the medical field, thermal imaging can be used for preliminary screening of certain diseases by detecting abnormal temperature patterns on the body.
