Instrument Features
Quick Test
Within one second, you can get both the Karat value and content value of your gold sample.
Accurate
Testing result of our XRF is comparable to the fire assay.
Non destructive
XRF test will not destroy your gold sample.
Multi-functional
Besides the gold, the non precious metals, such as Ni,Cu and Zn which are frequently used in the jewelries can also be simultaneously tested by our XRF. What’s more, our XRF can also be used to test the plating thickness of the gold plated jewelry.
Applications fields:
Jewelry factories
Jewelry shops
Pawnshops
Banks
Gold testing labs or fire assay labs
Refiners who buy and sell gold
