Hydrometer: meaning, definitions and examples
⚗️
hydrometer
[ haɪˈdrɒmɪtər ]
measuring instrument
A hydrometer is a device used to measure the specific gravity or density of liquids. It typically consists of a sealed glass tube with a weighted bottom that allows it to float upright in the liquid being tested. The specific gravity is determined by reading the scale on the stem of the hydrometer at the surface of the liquid.
Synonyms
density meter, specific gravity meter
Examples of usage
- Scientists use a hydrometer to determine the density of various liquids.
- Winemakers employ hydrometers to measure the sugar content in grape juice.
- A hydrometer can help in assessing the concentration of antifreeze in car radiators.

Etymology
The word 'hydrometer' comes from the Greek words 'hydro', meaning 'water', and 'metron', meaning 'measure'. It dates back to the late 17th century when devices for measuring the density of liquids were being developed. The concept of measuring specific gravity has its roots in Archimedes' principle, where the displacement of water was used to determine the volume and density of an object. Over the years, the design and functionality have evolved, leading to more precise and versatile instruments used in various fields, including chemistry, brewing, and marine sciences. The hydrometer continues to be an essential tool for scientists and engineers alike.
