摘要： An apparatus and method for measuring material buildup or fouling on a test specimen in which at least a portion of a temperature sensitive voltage output means is located proximate to a test specimen. The extent of fouling is determined by the change in a detected current or voltage signal resulting from the change in the heat transfer coefficient of the test specimen. The temperature sensitive voltage output means is at the same temperature as the temperature of the medium in which the test specimen resides and adjusts either a detected current or voltage signal to negate the effects of varying temperature of the medium on the detected signal.
