The present invention relates to a specific gravity meter for measuring the specific gravity of a product or raw material in the manufacturing field such as chemistry, pharmaceuticals, etc. In more detail, a plurality of samples placed in a cartridge are sequentially drawn out one by one and the sample By automatically measuring the specific gravity of the product, it is a technology related to an automatic specific gravity measuring machine that is quick and easy to inspect the quality of products or raw materials, and is convenient for the operator to carry and transport to the place where the specific gravity test is required.

In general, a specific gravity meter has various methods depending on a measurement object such as a solid, liquid, or gas, and most often refers to a liquid gravity meter. It is a form of measuring the specific gravity of a liquid from the mass of an object and the buoyant force it receives when it is in a liquid using Archimedes' principle.

Among them, most of the measuring instruments for solids use Jolly balance, and for liquids, Westphal balance, areopycnometer, hydrometer, etc. are used, and for gas, a glass balance is used. this is being used

In recent years, products produced by mixing various raw materials (silicon, pharmaceuticals, etc.) in the manufacturing field such as chemistry and pharmaceuticals are subjected to quality inspection based on quality requirements in the manufacturing process. According to the ratio, the specific gravity of the finished product and the raw material is measured.
