Introduction: Shenzhen Qunlong Instrument Equipment Co., Ltd. is committed to the research, development, production and sales of density testing instruments for various products, mainly engaged in hydrometers (densitometers), electronic balances (pycnometer), jewelry testing instruments (precious metal purity tester) and measuring instruments. I have accumulated many years' experience in specific gravity density, gained new insights into the specific gravity density testing methods of various materials, and put this into production. Take China as the basic point to serve the whole world. The product itself, in conjunction with the structure of the electronic balance, subdivides the archimedes principle into two categories: "impermeable hydrometer" and "permeable hydrometer", which is the most advanced instrument in the field of specific gravity testing and detection in China. Now the company's products have been widely used in powder metallurgy, precision ceramics, magnetic materials, rubber plastics, wires and cables, precious metal processing and manufacturing testing and other scientific research and experimental units, and have been fully affirmed and praised by the majority of users.
