Hydrometer. Hydrometer is an instrument for measuring relative density (specific gravity) of liquids. Its operation is based on Archimedes' principle. Here a hydrometer is being used to measure specific gravity of distilled water (1.0, left) and of sugar solution in water (1.1, right). First measurement is used to verify proper calibration of the hydrometer. Sugar concentration of 24 wt% is inferred from the second measurement. | |
