Thermocouples are temperature sensors widely used, but the reliability of the values indicated by them must be constantly checked. When the tolerable error limits are exceeded or when one wishes to increase the reliability of results, calibration should be performed. This text will address what are the main sources of errors in thermocouples and what are the ways to calibrate them. By a calibration, it was performed an improvement in LDA Arduino software, which now includes the Equation of a fitting curve in your source code, sending information to the system Lorscheiter Viewer correlated with a measuring instrument calibrated by a certified laboratory.
