Underwater weighing container and apparatus for measuring specific gravity

Abstract

This invention provides a weighing pan in liquid that has a small amount of liquid for measurement and can widen a sample mounting space. The weighing pan 1 in liquid comprises a cylinder 11 in which both the ends are open, an inward fillet 11a is formed at one end side, and a plurality of stoppers 11b are adhered to the inner surface at the other end side; and a mesh or porous circular bottom plate 12 inserted between the fillet 11a and the stopper 11b. The weighing pan 1 in liquid is dipped into liquid, a solid sample 2 is placed at the upper or lower side of the bottom plate 12, the weighting pan 1 in liquid is suspended by a suspension tool 13 for weighing the weight, and the specific gravity of the solid sample 2 is measured.

Description

technical field [0001] The invention relates to a submerged weighing vessel for receiving the weight or buoyancy of a solid sample in a liquid and a specific gravity measuring device for measuring the specific gravity of the solid sample. Background technique [0002] Generally speaking, in order to determine the specific gravity of a solid sample whose volume is unknown, the weight in the air of the solid sample and the weight or buoyancy in the liquid of the same solid sample can be used to measure the specific gravity, and it can be calculated from the relationship of the following formula (1): method of specific gravity. [0003] Specific gravity=weight in air / (weight in air-weight in liquid)=weight in air / buoyancy...(1) [0004] This method of measuring the air weight and liquid weight or air weight and buoyancy of a solid sample to calculate the specific gravity of the solid sample is adopted in many conventional specific gravity measuring devices as exemplified below...

Problems solved by technology

[0008] This shows that above-mentioned existing weighing dish in liquid and specific gravity measuring device obviously still have inconvenience and defect in structure and use, and urgently need to be further improved

In order to solve the problems of weighing vessels in liquid and specific gravity measuring devices, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products to solve the problem. The above-mentioned problems are obviously the problems that relevant industry players are eager to solve
