Does the GoldScreenPen indicate the carat number?

No. The GoldScreenPen measures the conductivity (like the GoldScreenBox) and is therefore ideal for counterfeit detection. Sub-alloys or the exact carat number cannot be measured with a carat number smaller than 21, because the conductance values ​​of these alloys only decrease very slightly with decreasing gold content.

Currently, the test acids or the density scale are the best methods to determine the carat number.

A device that fulfills exactly this function is currently under development and is expected around the end of 2021.
