The Qualitest range of advanced Gold Testers are the ultimate tools for the jewelry industry, gold & precious metal research labs, jewelry stores, banks, and pawn shops for accurate determination of the carat and purity of gold, silver, and platinum.

Applications

The gold testers can quickly, easily and accurately determine the purity of precious metals and gold karat by two weighings (By measuring the Specific Gravity): one with the piece in a water tank, the other normally. An internal computer does all the calculations for you.

Features/Advantages

Features

  • Gold Testers can check purity to confirm if a marked stamp on gold (platinum) is correct or not.
  • GKs are very useful to check the most common type of fake gold: lower purity than the marked stamp on gold (platinum).
  • Gold (platinum) which outside covered real gold (platinum), and inside with other metal can be detected.
  • Non-gold (platinum) metals can be distinguished.
  • It can be measured scrap gold at a time and show average purity.
  • Also function as a normal gram scale and Densimeter.
  • Wide karat range—from 9 to 24K
  • Advanced Model GKS-3000 can measure up to 3,000g, which makes it possible to measure ingots and statues.
  • Gold and Platinum measurement modes are available on GKS-3000.
  • Minimum specific gravity resolution 0.001 g/cm3 (0.0001 g/cm3), high resolution of the GKS-300 allows measuring minimum 2g samples.

Advantages

  • No acid, needles, or test stones needed
  • Leaves no scratches or stains on your gold after measurements
  • Easy operation in 20 Sec.
