QGMAYB-K Goldurity Analyzer (Water Drop Method)
Applicable fields: jewelry industry, pawnbroking industry, precious metal recycling, banks, jewelry testing centers, precious metal research laboratories... etc.
Principle: According to the standard GB/T1423 Method for Density Testing of Precious Metals and Their Alloys. Based on the Archimedes principle of the buoyancy method, accurately and quickly read the K number of gold, density and purity percentage, as well as the mixing ratio of precious metals.
Description:
1. Features a built-in Type-C charging port for connecting standard power banks, ideal for on-the-go power management and instant measurements;
2. Applicable to gold bars, jewelry, and other gold/platinum products (this principle is not suitable for testing hollow or inlaid gold jewelry);
3. Full-color 4.3-inch touchscreen with automatic data storage; test steps are reversible, enabling repeated data verification and simplifying user procedures;
4. Equipped with a Japanese-imported movement, it delivers precise measurements with color accuracy up to 99.99%, easy operation, and stable durability;
5. Digital display with direct reading—no manual calculation required—for instantly measuring gold purity and other metals 'density (specific gravity). Your gold remains free of stains or scratches after testing. In just 10 seconds, it accurately determines gold's K-value and color grade, as well as platinum's Pt value and density;
6. Built-in error compensation feature allows users to set their own error values;
7. Particularly suitable for use in conjunction with a spectral gold analyzer, ideal for gold collection and verification at banks, pawnshops, and gold shops, delivering enhanced accuracy through dual detection methods.
