Areometers of general purpose of the AON-3 type are used for measurement of density of liquid from 1000 to 1800 kg/m3.

In house conditions determination of the content of salt in a brine used for salting of massny products can be an example of use of areometers of general purpose of AON. Use of the areometer of general purpose allows to control concentration of salt in solution, so that the final product did not spoil. At the same time, concentration of salt in a brine has to make not less than 12%.
The brine is filled in in the cylinder for the areometer or other high vessel, with a capacity from 100 to 500 ml. Bring temperature to 10 degrees and carefully lower in it the areometer for measurement of density of the received solution from 1000 to 1200 kg / mz. For this purpose areometers of general purpose of AON will approach. The indication on the areometer is counted on bottom edge of a meniscus at the established position of the areometer in the cylinder. The areometer should not concern cylinder walls.
