These plain form hydrometers are available in a variety of models measuring specific gravity/relative density (g/cm⊃3;) of liquids lighter and heavier than water in various ranges from 0.690 to 3.000.
Plain-form hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.
