I have a hard time believing that the calibration error introduced by this junction would be anywhere near the error introduced by the galvanometer (meter movement) it is normally displayed on (considering that there are solder joints along the meter path INSIDE the unit). What is the accuracy of the thermocouple itself, 2-5%? Perhaps less accurate?
