Description
K Value Gold Densitometer/Gold Purity Tester
Product Overview

The MDJ-300K Gold Purity Tester utilizes advanced German sensors to determine precious metal purity through density detection. This non-destructive testing instrument quickly identifies genuine precious metals by displaying gold purity percentage, K value, density value, platinum content, silver purity, and other alloy compositions.

Applications

Ideal for use in:

  • Pawnshops and precious metal recycling
  • Jewelry manufacturing and retail
  • Banking and financial institutions
  • Mining operations
  • Jewelry testing centers
  • Industrial and research laboratories

Compliant with GB/T1423 noble metal purity determination standards, this instrument requires only two simple steps for accurate measurements without sample binding.

Precious Metal Detection

Detects all major precious metals including:

  • Gold (Au)
  • Silver (Ag)
  • Platinum group metals (Ru, Rh, Pd, Os, Ir, Pt)
