Why aren't thermocouples included in certificates of results?

Thermocouple data is generally not included with our digital devices. The accuracy of data measured with thermocouples is the combined accuracies of: the thermocouple itself; the temperature compensator; the linearization that approximates the thermocouple's characteristics; the mV range serving as the reference for the thermocouple input range; and the recorder mechanism. Also, with our digital devices, the linearization accuracy is fixed on the software, and the thermocouple accuracy is the determined as the total of the temperature compensation accuracy and the mV range accuracy. In products of certain recorder mechanisms, it also includes the accuracy of their recording position. Thus, even if the thermocouple temperature measurement data is not explicitly included in the test results certificate, we can sufficiently guarantee accuracy.
