Abstract. The differential and integral thermoeletric voltage of the thermocouple chromel-copper with 0.31 at.% Iron (KP-Cu+0.31 at.% Fe) is studied in the 4.2-300 K temperature range. A calibration Table with 1 K step is given and a polynomial description of the temperature dependence of the thermoelectric voltage is derived for the 5-300 K range.
