Hydrometer Liquids JLab

Hydrometer Liquids
These Hydrometers are designed to measure the specific gravity of light (700 to 1000) & heavy liquids (1000 to 2000).
The instrument consists of a standardized glass tube ending in a weighted glass sphere which allows the tube to stand erect when positioned in a liquid.
The lower the density of the liquid, the deeper the tube drops.
