This advanced gold karat tester is designed for precise measurement of precious metal purity and density without damaging samples. Ideal for various professional applications including:

• Pawnbroking and jewelry industries
• Banking and precious metal recovery
• Mining operations and research laboratories
• Jewelry testing centers

• Accurately displays gold K value, % content, and density
• Measures platinum % content and density value
• Determines silver % content and density value
• Analyzes other alloy % content and density values

• Precious metals: gold, pure gold, K gold, platinum, silver
• Mixed metals and alloy metals
• Jewelry items: rings, necklaces, bracelets, watchbands
• Gold ingots, bars, statues, and coins

Note: Cannot measure completely closed hollow products inlaid with precious stones or items with similar density.
