The hydrometer is a sophisticated precision measuring tool used to precisely measure and then determine the speed, weight, force and flow rate of liquids.
Both the bulb and the stem are made of glass, while in the bulb there is a portion of mercury or lead that will float when it is introduced into the liquid to be measured. And on the stem is the scale that indicates the density.
To measure the density of a liquid, it will be necessary to fill a test tube with the liquid in question and then introduce the hydrometer.
Although surely for most of us who are not dedicated to an industrial activity the hydrometer is not a common and common measuring instrument, it is important that we emphasize that in certain industries that produce food and beverages it is and also because of its Specific function turns out to be extremely useful when producing them.
Thus, dairy products and some alcoholic beverages such as wines and beers require the intervention of the hydrometer in their production processes since they are products that demand a certain density, so the hydrometer is ideal when it comes to accurately determining this. question.
Furthermore, such is the relevance that an instrument such as the hydrometer has in the production processes of the products indicated above that these industries have developed specific instruments adapted to the characteristics of the hydrometer.
According to what is deduced from the records of history, it is at French chemist Antoine Baumé who owes him the invention of the hydrometer, in the century XVIII. The invention would have had two alternatives, a hydrometer that was responsible for measuring liquids with characteristics heavier than those of water and another that measured densities smaller than those of water.
He even developed a scale to calibrate both models. Meanwhile, it should be noted that there are other models that are calibrated when the temperature is 60 degrees Fahrenheit.
