If you are still not familiar with what a hydrometer is all about, it makes sense to mention that this scientific instrument is often used in order to measure both the density and specific gravity of different liquids. Basically, all of these tools are composed of a special glass bulb. It needs to have a long skinny tube that must be connected to one end. People should know that this instrument is heightened with lead or mercury.

The tube portion of hydrometers must be labeled with a certain scale. When these are placed in some liquid, it is possible to see measured gravity. Users are able to calibrate this tool for specific liquids at certain temperature levels. They need to understand that the scale on it usually depends on their intended use. The lower the density, the more hydrometers are going to sink in the particular liquid sample. If you want to use them correctly, it is necessary to pour such samples into a tall glass cylinder. It is also possible to use the same container. You need to place the hydrometer in liquids vertically. The depth of its bulb flotation can be measured by means of a special scale on its tube neck.

A Variety of Applications

It makes sense to mention that there are different types of hydrometers that can be found in the modern market. Consumers need to choose the most suitable one based on their intended uses. It is advisable to understand that all of these tools may have different scales that usually vary in accordance with their use. For example, hydrometers that are designed for a variety of heavy liquids need to have their scale starting at one. When it comes to light liquids, they need to have the scale that is below one.

In addition, there are different battery hydrometers, the ones that come with a specific digital model. It is necessary to use them in order to measure the specific gravity of battery liquids. You can use them to be able to determine the charge and condition of the particular battery. There are many other hydrometers that you can find out there. The most common ones include sacharometers and alcoholometers. These are widely used to measure the density of sugar or alcohol. You can find all of these tools on the Internet or when visiting local stores.
