The laboratory deals with the measurement of the saturation vapor pressure of water and the new-generation refrigerant fluids. The high measurement accuracy*, ensured by the instrumentation used and the measurement method adopted, make it possible to obtain experimental data crucial for the implementation of EOSs that well describe the thermophysical properties of the mentioned substances.

*expanded percentage relative uncertainty between 0.06 % and 0.18 %, in the temperature range from 252 K to 273 K, regarding water and between 0.15 % and 0.60 %, in the temperature range from 274 K to 338 K, concerning refrigerant HCFO-1224yd(Z)
