den·si·tom·e·ter

(den'si-tom'ĕ-tĕr),
1. An instrument for measuring the density of a fluid. Synonym(s): densimeter
2. An instrument for measuring, by virtue of relative turbidity, the growth of bacteria in broth; useful in microbiologic assay of nutrients and antibiotics, phage studies.
3. An instrument for measuring the density of components (for example, protein fractions) separated by electrophoresis or chromatography, using light absorption or reflection.
4. An electronic instrument for measuring the blackening of radiographic film by x-ray exposure; used for film sensitometry, bone densitometry, measurement of line spread function (microdensitometer).
5. An instrument for measuring the extent to which a material absorbs or reflects light.
