For checking specific gravities of liquids such as battery acid and antifreeze.
Hydrometer measure the density of liquids.
You use a 'hydrometer'. -Usually found in the auto section,about $5 - 8.
Salinometer
Barometer is used to measure atmospheric pressure. Hydrometer is used to measure specific gravity.
A hydrometer can be used to find the specific gravity (relative density) of a liquid by determining how much water it will displace. Various calibrations are used for different kinds of liquids.
A hydrometer is used to find the specific gravity (or relative density) of liquids.
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
a Hydrometer is used to measure the density of a solution, by the use of a scaled float. typically it is used for battery acid.
hydrometer s used to check the acid in a dog's body
hydrometer
a hygrometer is used to measure the amount of Condensation as well as evaporation and a hydrometer is used to measure the specific gravity of liquids
