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.
Ideal for use in:
Compliant with GB/T1423 noble metal purity determination standards, this instrument requires only two simple steps for accurate measurements without sample binding.
Detects all major precious metals including:
