1. A method for testing the accuracy of a temperature probe exposed to a medium having a temperature of between about 2200°

  • F. and 3400°

    F., comprising the steps ofmeasuring the rate of change of the temperature readings of the probe after a temperature of at least 2000°

    F. is read,comparing the measured rate of change with a standard rate of change obtained from a properly operating probe, anddeclaring the temperature probe to be inaccurate whenever the rate of change deviates significantly from the standard rate of change.
