#chemical density
- Alcoholometry — A technical method and set of operations used to determine the concentration of ethyl alcohol in a hydroalcoholic mixture or a beverage. The process is based on measuring liquid density using an alcoholmeter or through precision refractometric and pycnometric methods, being essential in industrial quality control and custom duties.
- 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).
- Alcoholoscope — A simplified and rarer spelling variant for alcoholoscope; an optical apparatus or laboratory instrument used for the qualitative determination or visualization of the presence of alcohol vapors in a given environment. It is based on color reactions or refractometric deviations of light, historically used in preliminary analyses before the development of automated electronic systems.
