When thermocouples are used to measure the temperature of surfaces which are exposed to fluids at temperatures different from that of the surface, errors occur because of conduction of heat along the thermocouple wires. These errors have been analyzed and predicted in a previous report; the present report presents experimental results which verify this analysis.
