    Experimental study of Nusselt number on Rayleigh number dependence with using of cryogenic 4He gas requires precise measurement of the temperature differenceT 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.
