Areopycnometer
Definition
A hybrid laboratory instrument used for the high-precision measurement of liquid density or the specific gravity of chemical solutions. This device structurally combines the hydrostatic operational principle of the hydrometer (based on the volume of displaced liquid) with the rigid volumetric technique of the pycnometer, ensuring superior calibration and accuracy by partially eliminating errors caused by ambient temperature variations.
