HYDROMETER Meaning and
Definition
-
A hydrometer is an instrument used to measure the specific gravity or relative density of liquids. Specifically designed to determine the density of liquids, it consists of a long and narrow cylindrical glass tube with a weighted bulbous bottom that allows the device to float in a liquid. Constructed with a graduated scale, the hydrometer provides a numerical reading that corresponds to the specific gravity of the liquid being tested.
Hydrometers are commonly used in various industries to measure the concentration or purity of liquids such as acids, alkalis, and solutions. In the field of brewing and winemaking, hydrometers are used to measure the sugar content of the liquid, which is a crucial factor in determining the alcohol content that the liquid will yield. Additionally, hydrometers are employed in the petroleum industry to measure the density and viscosity of oil.
To facilitate easy and accurate measuring, hydrometers are usually calibrated and designed to work at a specific temperature, commonly 20 degrees Celsius. Any deviation from this temperature requires correction either through a table or adjustment scale provided with the instrument.
Overall, hydrometers play a vital role in different scientific and industrial applications, offering a straightforward and effective means to determine the density and composition of various liquids.
