Electronic Gold Testers are an easy, safe, and non-destructive way to test your gold and determine the karat purity of gold. With an Electronic Gold Tester you will see your gold testing results almost instantly. Gold testing machines vary in precision, with some testing in ranges ( 6K, 18K, 18K+), and others testing up to 24K.
Gold Testers are known to be significantly more reliable than other gold testing methods, gold testing equipment can even be used to test gold anywhere; whether it's in an office, a pawnshop, an estate sale, or a flea market! The sky's the limit!
There is also the added benefit of being able to test almost any type of gold: gold coins, jewelry, or scrap metal -- something that can't be accomplished with the acid gold testing method.
