Hydrometers
A hydrometer is an instrument that measures the specific gravity or relative density of a liquid in relation to water. They are typically constructed of a glass cylinder (similar to laboratory cylinders), complete with a weighted bulb that floats in liquid. Hydrometers are divided into two categories, those liquids that are heavier than water and those that are lighter than water.
