areometer
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.
