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.

GKS-300 is the basic model, suitable for gold and can measure the carat of gold specimens weighing between 0.001~ 300g.

GKS-3000 is the top of the line model suitable for gold, silver and platinum with extended weight capacity of up to 3,000 g.

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

  • Works only for solid metal pieces without set stones.
  • No acid, needles, or test stones needed.
  • Leaves no scratches or stains on your gold after measurements.
  • Wide karat range—from 9 to 24K.
  • Tests other precious metals such as platinum and silver.
  • Also functions as a normal gram scale.
  • 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 to measure minimum 2g samples.
  • Purity % and purity K (PT) are displayed at the same time (both GKS-300/GKS-3000).
  • GKS-300 comes equipped with wind shield.
