Hydrometers test specific gravity in a liquid/relative density they are used for anti freeze, batteries etc. They also test the buoyancy of water.
A hydrometer measures the specific gravity or density of a liquid, typically used to determine the alcohol content in a solution, such as beer or wine. By floating in a liquid, a hydrometer can provide a reading that indicates the concentration of sugars or alcohol in the liquid.
The hydrometer was invented in 1770 by Swiss mathematician and physicist Daniel Gabriel Fahrenheit.
The hydrometer will float higher in glycerin than in gasoline because glycerin is denser than gasoline. The level to which the hydrometer floats indicates the density of the liquid it is submerged in.
The property of water that causes the hydrometer to be read at the level of the meniscus is surface tension. The meniscus is the curved surface of the water in the hydrometer caused by the attraction between water molecules and the walls of the hydrometer. Reading at the bottom of the meniscus helps to ensure an accurate measurement.
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 commonly used to test the specific gravity of a forklift battery. This device measures the density of the electrolyte in the battery, which can provide information about the state of charge and health of the battery.
A barkometer is a hydrometer calibrated to test the strength of tanning liquors used in tanning leather.
It measured by the density of the size from the hydrometer.
The least count of a hydrometer typically ranges from 0.001 to 0.005 depending on the specific design and purpose of the hydrometer. This value represents the smallest incremental measurement that can be read on the scale of 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
A hydrometer is a device used to measure the specific gravity or relative density of liquids. In Hindi, a hydrometer is called "हाइड्रोमीटर" (pronounced as "haideromeetar").
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid

To measure specific gravity in a liquid using a hydrometer, you simply place the hydrometer in the liquid and read the value where the liquid surface intersects the scale on the hydrometer. This value indicates the specific gravity of the liquid.
