Note 1: Total digital accuracy of thermocouple measurement: analog/digital conversion accuracy +0.1 ℃ (cold end compensation accuracy)

Overall accuracy after using sensor matching function (transmitter + sensor)

Note 1: The sensors listed in the table are the most commonly used, stable and representative sensors in each temperature range. For details of accuracy in a wider temperature range, please consult the manufacturer.

Note 2: The thermocouple matching function is a patented technology and must be completed before leaving the factory.

Note 3: The accuracy of thermocouples in the table includes the accuracy of cold junction compensation and does not need to be superimposed separately.
