Abstract
A plug calibrator is a solid piece of metal with thermocouple or thermistor instrumentation embedded near a viewing surface. A heat source controls the temperature of the plug which is measured by the thermocouple and assumed to be that of the surface. An infrared imager views the surface obtaining a calibration at various temperatures. This paper reviews several designs for plug calibrators and their utility in quantitative analyses. Calibrator design parameters such as internal thermal resistance, location of instrumentation, surface quality and heat source location are discussed. The plug calibrator is a useful tool in quantitative analyses.
