The hydrometer is a measuring instrument for determining the density or specific gravity of liquids. The instrument is immersed in a liquid until the weight force of the displaced liquid corresponds to the weight force of the immersed body. Hydrometers are used, among other places, in laboratories, dairies or wineries (must scales) used. For accurate density measurement and to […]
ALLA FRANCE and the History of the Hydrometer The origin of the hydrometer is more vague, but also more ancient. The hydrometer works according to Archimedes’ principle, defined by the Sicilian mathematician (287 – 212 BC) as follows: “The upward buoyant force that is exerted on a body immersed in a fluid, whether fully or […]
