I believe that this has to do with comparitive relative densities of a. the liquid under consideration b. the actual hydrometeor.
It measured by the density of the size from the hydrometer.
The calculated specific gravity may be slightly different than the hydrometer reading. The calculated gravity is calculated using specific data while the hydrometer measures the liquid at a specific time and temperature.
A hydrometer consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. Mercury has a higher density, thus a lower volume for the same weight than lead. It is a toxic liquid metal, but also more dangerous and difficult to clear up the mess when a glass hydrometer is broken
A saccharometer is a hydrometer used to measure the sugar content of a liquid.
You don't need to. It already says on the bottle.
Hydrometer measure the density of liquids.
It measured by the density of the size from the hydrometer.
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.
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 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
Hydrometer
it is liquid
A thermohydrometer is actually a regular hydrometer that has a thermometer inside the float section. It is very similar to the regular hydrometer.
