Which gold tester is best for me?

That depends on the objects you want to analyse:

For classic investments (coins and bars), the GoldScreenBox in combination with calipers and precision scale is usually sufficient (also measures through packaging). For bars from 50 grams and upwards, we recommend the BarScreenSensor, for which the objects have to be unpacked.

In the jewellery sector, the measurement is somewhat more complex. In most cases, a combination of GoldScreenPen, density scale and test acid set is necessary for a meaningful analysis. The GoldScreenPen can also be used for smaller investment objects up to approx. 1 ounce.

As a wolfram detector, the magnetic scale is a cheaper alternative to the GoldScreenBox for gold objects from about 1/4 ounce up to 250 g. For those who want to focus entirely on gold and do not intend to unpack 100-gram bars, for example, the magnetic scale is a good choice.

For larger or irregularly shaped bars whose dimensions cannot be determined with sufficient accuracy with a caliper, the bar testing set is recommended.
