DH-300K Jewelry Tools Portable Gold purity Testing Machine Price
Application:
The gold purity tester is an instrument which can quickly distinguish the true and false of precious metals from the content. It can quickly display the percentage, K value and density value of gold purity without damaging the samples. It has the advantages of accurate measurement, simple operation, economical and practical. It is a good tool to distinguish the purity of precious metals from counterfeit ones.
It is widely used in pawnbrokers, precious metal recycling, jewelry houses, jewelry manufacturers, jewelry testing centers, industries, gold and Precious Metal Research Laboratories And other industries. According to GB / t1423, it is the most widely used method.
The gold purity tester can also measure the purity of other precious metals, such as platinum, silver, palladium, copper, rhodium, tin, platinum, gold, palladium, bracelet, gem, jade, etc
