AlfaMirage GKS-300 – High-Precision Gold & Platinum Purity Tester with 0.001 g Resolution

The AlfaMirage GKS-300 is a professional precious metal analysis device that combines maximum accuracy with advanced density measurement technology. Compared to the GK series, the GKS line offers an even finer resolution, enabling exceptionally precise purity evaluations - ideal for laboratories, refineries, jewelers, and precious metal dealers who require the highest level of measurement reliability.

With a resolution of 0.001 g and a capacity of 120 g, the GKS-300 delivers extremely detailed measurement results. It displays gold purity from 9 to 24 karats as well as platinum purity from Pt600 to Pt1000 - each also shown in percentage (up to 99.9%). By analyzing specific gravity, the device reliably detects counterfeits, incorrect alloy compositions, and materials with concealed metal cores.

Features:
• Determines gold purity from K9 to K24 and displays purity in percent (up to 99.9%)
• Platinum analysis from Pt600 to Pt1000 including percentage display
• Detects gold and platinum with lower purity than the stamped value
• Identifies gold-plated or platinum-plated items as well as materials with a non-precious metal core
• Specific gravity analysis - one of the most reliable methods for authenticity testing
• Density display from 1 to 0.001 g/cm³ (depending on sample weight)
• No chemical tests, no scratches, no damage to the material
• Measuring range 0.001 - 300 g
• Ideal for small jewelry pieces, fine gold, laboratory samples, and high-value precious metal components
• Calculates average purity when testing multiple items simultaneously
• Ready for immediate use thanks to the included calibration weight

Important – Not suitable for:
• Hollow jewelry pieces
• Items containing gemstones (must be removed before testing)
• Materials with a density very similar to gold or platinum
