Laboratory Baume (°Bé) Meter Glass Densitometer 0-70 High Precision Salinity Hydrometer Glass Liquid Hygrometer Pack of 5/PK

Baume (°Bé) Meter 0-70°Hydrometer is based on the law of Archimedes and objects floating on the surface of the balance of the conditions made of liquid density is an instrument. Concentration of acid at a standard temperature of 25 degree to measure the specific gravity (density) of the liquid.CompositionWith a closed glass tube, one end of uniform thickness, the inner wall attached to the scale paper, the other end of a slightly bulky bubble-like the glass tube can be detected in the liquid vertical immersion To a sufficient depth, and can be stably floated in the liquid, that is, when it is subject to any shaking, can automatically restore to a vertical rest position. When the hydrometer is floating in a liquid, its gravity is equal to the gravity of the liquid it drains. So in different liquids immersed in different depths, the pressure is different, hydrometer is the use of this relationship scale.There are two kinds of Baume hydrometer: one is called heavy table, used to measure the liquid than the weight of water; the other called the light table, used to measure the liquid than light water. After measuring the Baume degree, from the corresponding chemical manual of the table can be easily found in the percentage of the concentration of the solution. The specific gravity of the general hydrometer can be converted to Baume's degree by the following formula. In the formula, D1 represents the specific gravity of the liquid heavier than water (numerically equal to its density) and D2 represents the specific gravity of the liquid lighter than water. Baume degree value is large, easy to read, so in the production of commonly used Baume degree that the concentration of the solution (a certain concentration of the solution has a certain density or specific gravity).Measure the depth of the liquid than the length of the hydrometer, so that the hydrometer suspended in the liquid, the horizontal plane and the scale of the degree of intersection is the liqu
