Thermocouple Accuracies

The accuracy of a thermocouple depends on many factors including but not limited to electrical interference and the purity of the metals used.

Note: The accuracy of a thermocouple depends on many factors including but not limited to electrical interference and the purity of the metals used. Thermocouples are supplied to meet the tolerance specified for temperature above 32°F.,Accuracies are estimates given at fixed points, they do not apply to temperature ranges and are intended only as examples to give a general idea of accuracies. Consult REOTEMP if a specific accuracy is needed at a temperature not listed in the above table.
