Package List:10 x Hydrometer10 x Storage TubeHow to Use:1. Place the hydrometer vertically in the liquid at a standard temperature, usually 20 degrees, and once stabilized, the reading on top, which lies flush with the liquid surfaces, is dissolved content.2. The measurement of the content of the solution is usually done using a hydrometer. A hydrometer is manufactured according to the principle of different dissolved concentrations with different specific gravity and different volume of liquid displaced by a floating body sinking into the liquid. When a hydrometer is placed in a liquid, the higher the concentration of the solution, the more the hydrometer sinks and the lower the specific gravity. On the other hand, the lower the concentration of the solution, the fewer sinks of the hydrometer and the greater the specific gravity. 1) we accept Alipay, West Union, TT.
