The objective of the present study was to investigate the effect of fouling on the accuracy of temperature measurement. When a thin scale layer is deposited on a temperature-measuring probe, the temperature reading can be in error by several degrees in spite of ± 0.1 K resolution of the probe. This erroneous temperature reading can pose a serious problem in the evaluation of heat exchanger performance and in the operation of an automated process control system.
