Hydrometer ADB-1 is designed to measure the density of drilling, cementing, cement and any other solutions, as well as liquids and slurries, and neutral to polyethylene. (Source: apmex). Hydrometer - in physics is the name of the device, which serves to determine the density and, consequently, the specific weight of bodies. The device is a hydrometer is based on the hydrostatic law (Archimedes law), in which each body is floating in the liquid so deeply immersed in it, that the weight the displaced fluid is equal to their total weight of the floating body. Hydrometer looks like a "float glass", widening at the bottom and filled with steel shot or a special heavy weight (ballast). Instruments which measure high density, have a large ballast. Besides the usual, there are special hydrometers. They are designed for certain types of liquids: alcohol, sugar solutions, etc.

In such a hydrometer scale scaled in weight or determined by the volume percentage of the product. To determine the relative weight of the liquid, pour it into a glass vessel (cylinder) and carefully lower the hydrometer there. Once the hydrometer will take the correct position, counting is carried out readings on the scale. For the amount of weight value is, against which the fluid level is established, considering the top or bottom edge of the meniscus, depending on the performance of the hydrometer. The device consists of hydrometer and a bucket with a lid. A bucket is a container for the working of water, which is immersed hydrometer with a solution. The cover is designed for sampling of the solution.

In the hydrometer includes measuring cup, float, consisting of cover and bottom, the rod and bears on its core (from 0.8 to 2.6) and the correction (from 0.2 to 1) scales, and a removable cargo. Beaker has two cavities: the measured sample solution and the compensation chamber. In the compensation chamber placed metal ballast needed for the stability of submerged unit. The ballast is insulated from the environment with plastic plug. Provides buoyancy float the hydrometer. The bottom float designed to remove excess solution from the measuring cup up to the calculated volume. The rod is made of standard tube and attached to a float.
