The hydrometer allows you to measure the density of a liquid. They can be both general purpose and specialized. They are used in various fields of national economy. General-purpose devices can determine the density of liquids, which is in the range of 700 to 2,000 kilograms per cubic meter. They are manufactured in accordance with the requirements of the standards. The hydrometer AON-1 can be attributed to this category of measuring instruments. It is about him that will be discussed in this article.
Product Overview
General-purpose hydrometers AON-1 are suitable for working with liquid substances, the density of which is from 700 to 1840 kilograms per cubic meter. This is a universal meter that is reliable and easy to use. He is able to cope with all the tasks assigned to him.
A hydrometer is produced in accordance with the requirements of GOST 18481-81. The quality of all manufactured meters is checked at the factory. This test is required. You can learn about its results from the certificate, which is included in the set of general-purpose hydrometers AON-1.
When storing and transporting the device, certain conditions must be met. In such situations, the meter should be in an upright position so that the ballast is at the bottom. For protection, the hydrometer is placed in a special tube. This will protect him from accidental bumps. Mechanical damage can lead to cracks and, as a result, damage to the ballast.
Scope of measurement
Among the liquids studied by the device, the following can be distinguished:
- Other compounds of various nature.
In addition, a universal meter can determine the density of more viscous solutions. A striking example is mortars: cement, putties, concrete, and so on.
AON-1 hydrometer is used in various fields. Such a meter is used, for example, at the enterprises of the alcohol, oil, and sugar industries. They are found in laboratories involved in analyzes of various kinds (chemical, biological and industrial).
Device and principle of operation
Externally, the meter is a tube expanded at the bottom. Glass is used as a material for its manufacture. In the lower (wide) part is the ballast. A measuring scale is applied on the surface of the upper (narrow) part.
The principle of operation is very simple. The meter is lowered into the test fluid. A deeper immersion of the meter in a substance is characteristic of liquids with a lower density. This is taken into account when applying the scale to the handset. The upper part of the scale shows lower values, and the lower - large. The density value is determined visually. In this case, the readings look at the lower meniscus.
Main characteristics
The AON-1 hydrometer is small in size and light. Its length is not more than 170 millimeters with a tube diameter of 20 millimeters. The diameter of the rod is 4 millimeters. The scale is plotted almost a quarter of the length of the entire meter. Its length is 44 mm.
The scale is applied with a gradation of 1 kilogram per cubic meter. Depending on the possible density of the measured liquids, the AON-1 hydrometer has a large number of modifications. They can be seen in the table in the figure below.
It is recommended to use the device at an ambient temperature of 18-22 degrees. When using it in other conditions, it is necessary to make appropriate corrections for temperature changes (carry out a calculation).
A set of hydrometers allows you to measure density in all liquids. There is no need to purchase density meters.
