Alfa Mirage Precious Metal Tester GKS-3000

Discover the truth beneath the surface. While electronic pens and acid drops are great for surface testing, how do you know if a thick gold bar or heavy chain isn't secretly filled with cheap metal on the inside? The Alfa Mirage GKS-3000 solves this completely. Using the scientifically proven method of water density (hydrostatic weighing), this premium Japanese-engineered machine calculates the exact purity of your gold and platinum all the way through to the core. It is the ultimate truth-teller for serious investors and scrap buyers.

Why You’ll Love It

• Catches the "Deep" Fakes: This is your ultimate defense against heavy gold plating. Because it measures density, it easily detects items that are coated in real gold on the outside but filled with cheap, non-precious metals on the inside.

• Verify the Stamp: Does that necklace say "18K"? Put it to the test. The clear display instantly shows the true karat (from K9 to K24) and Platinum purity (600-1000 & %) so you know if the manufacturer's stamp is telling the truth.

• Bulk Scrap Testing: Time is money! Instead of testing one link at a time, you can place a whole handful of scrap gold into the water tank to get an instant average purity reading for the entire batch.

• Dual-Purpose Precision: When you aren't testing for purity, this machine doubles as a highly accurate, standard digital gram scale and a general densimeter.

Important Testing Limitations (Please Read)

To ensure you get the perfect tool for your needs, please note that because this machine relies on water displacement (density), it CANNOT test the following items:

• Hollow Jewelry: Water cannot enter the hollow spaces, which will skew the density reading.

• Jewelry with Gemstones: Stones have different densities than metal. (Stones must be removed prior to testing).

• Metals with Identical Density: Cannot distinguish metals that share the exact same density as gold (such as Tungsten).
