Electronic gold tester is an easy, safe, and non-destructive way to test for gold and determine the karat purity of gold. With an electronic gold tester, you will see the results of your gold testing almost instantly. While gold testing machines vary in precision, with some testing in ranges (e.g. 6K – 18K, 18K+), and other testing throughout the spectrum of 24K, gold testers are known to be significantly more reliable than other gold testing methods, and gold testing equipment can also be used to test gold anywhere, whether it be in an office, a pawnshop, an estate sale, or a flea market. There is also the added benefit of being able to test almost any type of gold: gold coins, jewelry, scrap metal, something that can’t be accomplished with acid gold testing method.
