Does the GoldScreenPen indicate the carat number?

No. The GoldScreenPen measures the conductivity (like the GoldScreenSensor) and is therefore ideal for counterfeit detection of coins, bars and silverware. 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.

The CaratScreenPen measures the carat number of gold objects, and therefore is the best method to detemine the carat number. The Goldanalytix test acids or the density scale are also methods to determine the carat number.
