Hydrometers are graduated floating devices that measure the densities of liquids. Hydrometers are commonly used in the making of wine, beer, and spirits to monitor the fermentation process and are also used by environmental scientists to monitor the concentration of salt and impurities in water. Commercial hydrometers are tubes of glass, weighted with metal shot, but you can make a simple hydrometer with materials you can find in a grocery, hardware, or sporting goods store and use it to test the density of water with various salt concentrations. | Hydrometers are graduated floating devices that measure the densities of liquids.
