Infrared (IR) Thermography
IR thermography came on the scene as a viable temperature measurement technology for industry in the 1950’s, but with significant limitations. Most of the early effort was directed toward detecting temperature differences, not necessarily acquiring accurate temperature measurement. Sunlight and reflection interfered significantly with accurate measurement outdoors.
Today, IR technicians using state of the art digital equipment can provide accurate temperature measurement. IR technology has advanced to the point where a minimal amount of training is required to become proficient in the use of the latest hand held cameras. However, proper interpretation of the data collected by the camera requires a skilled and experienced technician. IR technology is still relatively new and there are only a few experienced service companies and technicians available. As a result, some industrial users purchase their own IR equipment and train an in-house technician to perform infrared thermography.
