Experimental study of Nusselt number on Rayleigh number dependence with using of cryogenic 4He gas requires precise measurement of the temperature differenceT between the top and the bottom plates of the convection cell. A special calibration device was adapted and used for comparative calibration of germanium temperature sensors. This device enables to compare up to four sensors within the temperature range of 4.3 K – 40 K.
