Instrument used in measuring specific gravity / relative density of liquids.
Hydrometers are used in different states, such as a lactometer for measuring the density (creaminess) of milk, saccharometer for measuring the density of sugar in a liquid, or an alcoholmeter for measuring higher levels of alcohol in
The demonstration method is the ratio between density of the liquid and the density of water.
The hydrometer is made up of glass material, cylindrical stem and a bulb contains mercury/ lead shot to make it float upwards.
