Abstract. A new high-pressure densimeter which employs the direct weighing technique was constructed to measure compressed liquid density. The reliability of the apparatus was confirmed by comparing the measurements for pure fluids with reference data. The compressed liquid densities for binary mixtures of difluoromethane and pentafluoroethane were measured in the range 283 - 333 K and near the saturation line up to about 20 MPa. It was found that these results were in fair agreement within ±0.3% taking into account the estimation errors of temperature, pressure, and composition with the reference data in the high density region.
