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.
An instrument used to measure the Specific Gravity (or Relative Density) of a liquid is called as a Hydrometer. It is the Ratio of the density of the liquid to the desnity of the fresh water (i.e. 1.000). The instrument consist of a glass chamber with Lead Shots or Mercury filled at the bottom or the base, to make it float upright.
ghh
it is liquid
a hydrometer checks the state of battery charge using specific gravity.
hydrometer
to check how much electrolyte is present in the battery
It is an instrument to measure or gauge density of gravity.
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
Hydrometer measure the density of liquids.
It measured by the density of the size from the hydrometer.
The function of a hard glass test tube is heating a substance. The glass is resistant to chemicals and it can withstand pressure and heat.

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.
