Hydrometers

Hydrometers are instruments that measure the specific gravity or relative density of a liquid in relation to water. Hydrometers are typically constructed of a glass cylynder (similar to laboratory cylinders), complete with a weighted bulb that floats in liquid.

To operate the hydrometer, you place it in the liquid and take a reading from where the hydrometer breaches the surface. This reading will give you the specific gravity of the water. In high density liquids the hydrometer will float much higher than in low density liquids.

Specialised variants are available depending on their application. For example, a lactometer is used to check the purity of dairy products whereas an alcoholmeter indicates the alcoholic strength of a liquid (where water and alcohol have been mixed).
