The gold purity tester YY-300K uses German imported sensors and converts the precious metal purity by detecting the precious metal density; it is an instrument that quickly distinguishes the true and false of precious metals from the content, without damaging the sample, and can quickly display the percentage of gold purity% and K , Density value, platinum% content, density value, silver purity%, density value,% content and density value of other alloys.

Widely used in pawn shops, precious metal recycling, jewelry silver buildings, banking, mining, jewelry manufacturers, jewelry testing centers, industries, gold and precious metal research laboratories and other industries. It conforms to GB / T1423 precious metal purity determination standard. It is currently a widely used detection method. This product does not need to bundle test samples.
