Very Important!
Due to the limited function determined by the principle.Following gold type can't be tested by gold density meter.
(1)Gold has any decoration.
(2)Gold has the painting.
(3)Gold inside is hollow.
(4)Plating gold.
Following gold type has high requirement for the operation:
(1)Gold with complex structure
Here is some examples as following.We would not like to recommend you to test this kind of gold by using the gold density meter.
