Description

Technical Field

[0001] The utility model relates to the technical field of density measurement, in particular to a density meter. Background Art

[0002] When measuring the density of a solid with an irregular appearance, the volume and mass of the solid need to be measured separately according to the density calculation formula. Currently, indoors, staff will use a balance to weigh the mass of the solid, and then immerse the solid in a measuring cup filled with water. The volume of the solid can be calculated based on the change in water level, and thus the density of the solid can be calculated. However, due to the surface tension of water, there will be a certain depression between the edge of the liquid surface and the inner wall of the measuring cup, and when the solid is placed in water, part of the water in the measuring cup may splash onto the outside or inner wall of the measuring cup, which will result in an inaccurate reading and affect the calculated value.

[0003] There is another method in the prior art, which is to measure the weight of the solid in the air and the weight in pure water with a density of 1kg / L respectively, and then use the two weight values ​​for calculation to obtain the density of the solid. However, this type of device requires water to be added to the container through a water pump, and the device is equipped with a computer, display screen, etc. for calculation. It has many components, complex internal circuits, and high costs. It is suitable for indoor environments. When outdoor prospectors use it outdoors, such as address exploration, archaeological analysis, etc., it is inconvenient to carry it outdoors to measure and record the density of irregular solids. The above two measurement methods are inconvenient for outdoor workers to use. Utility Model Content
