#areometru
- Alcoholmeter — A metrological instrument used to determine the concentration of ethyl alcohol in a hydroalcoholic solution or a spirituous beverage. It usually functions on the hydrometer principle, measuring the specific density of the liquid, which varies according to the amount of ethanol present, being graduated directly in percentages of volume (alcohol proof or ABV).
- Alcoholmeter — A simplified form or spelling variant for alcoholmeter or alcoholimeter; a graduated instrument used to measure the density of water and ethyl alcohol mixtures, indicating directly the volumetric concentration of ethanol (alcohol proof or ABV). It is widely used in industrial and artisanal spirits production to monitor distillation processes.
- Areometric — Belonging or relating to an hydrometer (areometru), or based on measurements carried out using this hydrostatic instrument utilized to determine the relative density of liquids or the concentration of solutions. In a structural technical sense, it describes a method, a graduated scale, or an experimental procedure based on Archimedes' principle, used in laboratories for analyzing industrial fluids, dairy products, or alcoholic beverages.
- Hydrometer — A measuring instrument consisting of a sealed glass tube, equipped at its lower part with a ballast bulb filled with shot or mercury and at its upper part with a thin graduated stem, used for the direct determination of a liquid's density or specific gravity. In a structural sense, its operation is based on variable vertical immersion in the fluid depending on its density, the level to which the stem sinks indicating the desired value on the scale.
- Areopycnometer — A hybrid laboratory instrument used for the high-precision measurement of liquid density or the specific gravity of chemical solutions. This device structurally combines the hydrostatic operational principle of the hydrometer (based on the volume of displaced liquid) with the rigid volumetric technique of the pycnometer, ensuring superior calibration and accuracy by partially eliminating errors caused by ambient temperature variations.
