Product Story

This is the device that easily authenticates karat grades of gold. Without the messy gels, staining chemicals, or dangerous acids used by other authentication techniques, the authenticator's pure gold-tipped electrode measures the electromagnetic frequency produced by a tested object using a safe saline solution that acts as an electrolyte. Pure gold will yield zero volts - its tested karats are indicated immediately by a panel of LEDs that range from six to 24 karats. Non-gold, gold plate, or gold-filled objects will reveal their true natures as "NA." It can also distinguish between platinum, tungsten, stainless steel, and white gold. Fully portable, the lightweight device stores and carries easily in an included rubberized case. Probe provides up to 5,000 tests. Includes 14K gold calibration chip, 9-volt battery, and diamond-dusted file.  10" L x 10" W x 2 1/2" D. (2 lbs.)
