• ✔【Professional-Grade Non-Destructive Purity Testing】The gold density meter employs high-precision buoyancy method technology, enabling non-destructive and rapid determination of the density and purity of precious metals such as gold, silver, platinum, palladium, and karat gold, with an accuracy of up to 0.001 g/cm³. No sample cutting or damage is required, but it can only test solid samples and is not suitable for testing hollow items or inlaid gemstones.
• ✔【Multi-Parameter Display】The gold density meter is equipped with a bright digital LCD screen, suitable for gold (density/volume/purity/karat number), platinum, white gold (density/volume/PT value), karat gold (density/volume/purity), silver, palladium, and other precious metals (density/volume/purity). Results are intuitive and accurate, helping you quickly determine the authenticity of precious metals and whether their purity matches the label.
• ✔【High-Precision Sensor】The precious metal detector incorporates a high-performance microprocessor and a high-precision weighing unit, featuring low temperature drift, automatic zero-point tracking, and overload protection, ensuring laboratory-level measurement stability and repeatability. It also provides audible/buzzer alarm prompts for convenient batch and rapid screening.
• ✔【Portable】The precious metal density analyzer has a built-in rechargeable battery, making it more convenient to carry and providing a long standby time. It is ideal for jewelers, pawnshops, and dealers, offering extended standby time and a convenient operating experience even while traveling or in areas with unstable power.
• ✔【Widely Applicable Scenarios】The metal density analyzer is not only suitable for various precious metals such as gold, platinum, silver, karat gold, and palladium, but can also be used for density analysis of various materials such as rubber, ceramics, and alloys.
