A state-of-the-art survey of portable thermal infrared instrumentation used for building diagnostics, plant maintenance and industrial process control is presented. The thermal infrared instrumentation is divided into three generic classes with a description of each class, its advantages and limitations and typical applications. Photographs of typical thermal infrared devices and systems in each class are presented.
