Hydrometers test specific gravity in a liquid/relative density they are used for anti freeze, batteries etc. They also test the buoyancy of water.
Hydrometer measure the density of liquids.
The hydroscope (also called the hydrometer) is thought to be invented by Hypatia of Alexandria. If this is true, the first hydroscope was invented in the 4th century.
it is liquid
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 measure the density of a solution, by the use of a scaled float. typically it is used for battery acid.
That's a 'hydrometer'.
A barkometer is a hydrometer calibrated to test the strength of tanning liquors used in tanning leather.
Hydrometer measure the density of liquids.
It measured by the density of the size from the hydrometer.
The hydrometer and the smaller "dewcheck" for field work each have articles in Wikipedia.org, "The World's Encyclopedia"
they are many tests to be conducted when we are going to construct a new road such as: - sieve analysis - hydrometer tests(not necessary) -compaction test - CBR test -sand cone test - abrasivity losangeles test - Standard penetration test - standard proctor test
Salinometer
The hydroscope (also called the hydrometer) is thought to be invented by Hypatia of Alexandria. If this is true, the first hydroscope was invented in the 4th century.
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
A hydrometer is used to find the specific gravity (or relative density) of liquids.
a hydrometer checks the state of battery charge using specific gravity.
a mathimatical term called a unit of hydrometer is what the study of gravity and other measurements
