    • n densimeter An apparatus for ascertaining the specific gravity or comparative density of a solid or liquid, as metals, gunpowder, or sea-water. That used for testing the density of gunpowder consists essentially of a vessel in which the gunpowder is weighed in connection with mercury. The vessel is first partially filled with mercury by creating a vacuum; it is then emptied and a known weight of powder is placed in it, and the mercury again added under the influence of the same vacuum, less being admitted, however, in consequence of the space occupied by the powder. A comparison of the amount of mercury admitted with the weight of the powder gives the specific gravity of the powder. The optical densimeter of Hilgard consists of a glass prism for holding salt water, and a collimating telescope for examining a ray of light passing through the water in the prism, the refraction of the light giving the density of the water by comparison with the known angle of refraction of distilled water or sea-water of a known density. Hitch's densimeter is used for ascertaining the density of syrups while boiling. See salinometer.
