The measurement principle is based on an optical evaluation of volume changes of supercooled liquid enclosed in fused silica capillaries. The apparatus allows for accurate measurements of density relative to density at the reference temperature (e.g., 298.15 K) and given pressure. An overview of the apparatus, measurement and calibration procedures are presented together with new results for the density of supercooled ordinary water, heavy water, and standard seawater. The new data in temperature range from 253.15 to 298.15 K and pressures up to 100 MPa are compared with the IAPWS thermodynamic property formulations and relevant literature experimental data.
