A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.
What are the uses of hydrometer?
- The specific gravity of a liquid is the density of that liquid divided by the density of water (in the same units).
- Measuring low-density liquids such as gasoline, alcohol and kerosene.
- Batter hydrometer for lead-acid battery.
- Urinometer is a type of hydrometer for urinalysis.
How does a hydrometer work for alcohol?
Most homebrewers measure alcohol content using a simple tool called a hydrometer which measures the density of liquids. During the fermentation process, yeast converts sugars into alcohol. ... By measuring the density before and after fermentation, you can calculate how much alcohol is in the finished beer.
