A hydrometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy.

• They are typically calibrated and graduated with one or more scales such as specific gravity.

• A hydrometer usually consists of a sealed hollow glass tube with a wider bottom portion for buoyancy,
