densification

n. an increase in the density of something.
Syn. -- compaction, compression, concretion. [ WordNet 1.5 ]

Densimeter

n. [ L. densus dense + -meter: cf. F. densimètre. ] An instrument for ascertaining the specific gravity or density of a substance. [ 1913 Webster ]

densitometer

n. 1. an instrument for determining optical or photographic density. A variety capable of measuring optical density of a sample at a number of different wavelengths, is called a spectrophotometer. [ WordNet 1.5 ]

2. same as densimeter. [ PJC ]

densitometry

n. measuring the optical density of a substance by shining light through it and measuring the intensity of the transmitted light. [ WordNet 1.5 ]

Density

n. [ L. densitas; cf. F. densité. ] 1. The quality of being dense, close, or thick; compactness; -- opposed to rarity. [ 1913 Webster ]

2. (Physics) The ratio of mass, or quantity of matter, to bulk or volume, esp. as compared with the mass and volume of a portion of some substance used as a standard. [ 1913 Webster ]

☞ For gases the standard substance is hydrogen, at a temperature of 0° Centigrade and a pressure of 760 millimeters. For liquids and solids the standard is water at a temperature of 4° Centigrade. The density of solids and liquids is usually called specific gravity, and the same is true of gases when referred to air as a standard. [ 1913 Webster ]

3. (Photog.) Depth of shade. Abney. [ 1913 Webster ]
