Liquid phase pvT properties of 1,1,1,2,3,3,3-heptafluoropropane (R-227ea) and HFE-7100 were measured precisely using a constant-volume cell. The pvT property of R-227ea was measured in the temperature range of (266 to 313) K and the pressure range of (0.823 to 17.014) MPa. The pvT property of HFE-7100 was measured in the temperature range of (275 to 303) K and the pressure range of (0.273 to 19.135) MPa. The temperature standard uncertainty was estimated to be 2.3 mK, the pressure standard uncertainty was estimated to be 15 kPa, and the density relative standard uncertainty was estimated to be 0.001. The experimental data for R-227ea were compared with an equation of state with a root-mean-square relative difference of 0.0003 for density. The liquid HFE-7100 pvT data were compared with available literature values, and the results show good agreements.
