HEIHEIZI Automatic Gold Testing Kit - Digital Density Meter (300g/600g/1200g) for Accurate Measurement of Gold, Silver, Platinum, And Plastics - 0.01g/0.005g Precision Detection,MDJ-600S

【Electronic Gold Purity Tester】Based on the Archimedes water displacement principle, it offers precise density resolution down to 0.01g/0.005g and a weighing range of 0.01g~1200g/0.005g~600g. Factory-calibrated for reliable measurements, it helps you accurately determine density and quickly estimate gold purity and other precious metals, providing key data for material value assessment. 【LCD Solid Density Meter】Features a large LCD display for clear readouts (weight, density, etc.). Combined with a high-sensitivity sensor, it ensures intuitive readings and fast, accurate measurements. Simple operations significantly boosts testing efficiency. 【Multi-function Tester】Automatically calculates and directly displays density values, eliminating manual calculations. Boasts auto-zero tracking and overload protection for stable measurements and enhanced instrument durability. Suitable for density testing of gold, silver, platinum, and various solid materials. 【Measuring Principle】: The electronic density meter is based on GB/T533, ISO2781, according to ASTMD297-93, DIN 53479, ASTMD792, D618, D891, ISO1183, GB/T1033, ASTM, D792-00, JISK6530, ASTM, D792-00, JISK6530. Using the buoyancy method of Archimedes' principle, accurate direct reading of the measured value. The electronic solids densitometer has temperature compensation settings and solution compensation settings. 【Wide Range of Uses】Electronic Solids Densimeter is widely used for rubber, plastic, wire and cable, food, composite material, cosmetics, shoe material, glass, precious metal hardware recycling... Other industries. The average weight of the samples in the air, the average weight of the water and the density and volume of the samples of solids, particles, thin films, floating bodies and powder bodies can be read out directly.
