ABSTRACT:
A method and system for testing the accuracy of a thermocouple probe exposed to a medium having a temperature of between about 2200.degree. F. and 3400.degree. F. is provided that includes the step of measuring the rate of change of the temperature readings of the probe after a temperature of at least 2000.degree. F. is read, and comparing the measured rate of change with a standard rate of change obtained from a properly operating probe. Both the method and the system are advantageously capable of determining whether the temperature readings of a thermocouple in use in a steel production plant are accurate without the need for comparative readings from other thermocouple probes.
