n: an instrument with a graduated stem, used to determine the gravity of liquids. The liquid to be measured is placed in a cylinder, and)he hydrometer dropped into it. It floatsat a certain level in the liquid (high if tI1e liquid is light, low if it is heavy),and the stem markings indicate the gravity of the liquid.

n: a floating instrument for determing the specific gravity or density of liquids, solutions and slurries. A common example is the mudwate hydrometer used to determine the density of mud

an instrument that is dropped in a liquid to measure its specific gravity.
