areometer

areometer

A scientist uses an areometer to measure the density of a liquid.

Definition

Noun: An instrument used to measure the specific gravity (relative density) of liquids. It typically consists of a weighted, sealed glass tube that floats upright in the liquid; the depth to which it sinks indicates the density.

Usage Examples
  • (An instrument for measuring liquid density.)
  • (Practical application in measuring specific gravity.)
Advanced Usage
  • "Areometer reading": the numerical value obtained from the scale on the instrument.
    • The areometer reading showed a specific gravity of 1.025. (The measurement of density.)
Variants and Related Words
  • Areometric (adj): relating to or involving an areometer.
    • The areometric analysis confirmed the liquid's purity. (Pertaining to density measurement.)
  • Areometry (n): the science or practice of measuring specific gravity using an areometer.
    • Areometry is essential in quality control for many industries. (The field of density measurement.)
Synonyms
  • Hydrometer: a more common term for the same type of instrument, especially used for measuring density of liquids.
  • Densimeter: an instrument for measuring density, often synonymous with areometer.
