#proof measurement
- 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).
