The CaratScreenPen is a gold tester that shows you the carat number of gold jewellery - fast and simple. It allows you to establish the gold content and detect under-alloying directly when you buy. Thinly gold-plated costume jewellery is even distinguished from real gold jewellery when measuring with the CaratScreenPen.
The GoldScreenSensor allows you to check the authenticity of precious metal coins and bars from 1/4 ounce to approx. 2 ounces (depending on geometry and material). The fast result output and detection of counterfeits made of tungsten, molybdenum and more makes the GoldScreenSensor the ideal precious metal tester for private investors and precious metal traders.
