Abstract: Construction and function of the apparatus for measurement of the equilibrium values of temperature and pressure in heterogeneous systems containing gaseous phase including water vapour by a static method are described. The main parts of the equipment are the furnace with adjustable temperature gradient and adjustable pressure of the gaseous phase and the set of closable carriers of samples. The apparatus allows to measure the equilibrium temperatures in the range from 25 °C to 500 °C with the error of 2°C. When the gaseous phase consists of water vapour the error in the determination of its equilibrium pressure changes from 0.02 kPa at the pressure of 1.7 kPa to 0.7 kPa at the pressure of 90kPa.
