Err on the side of caution with simple gold testing and save your money!

Are you always on the alert for fake gold coins, bars etc.? But how to test gold? With the handheld devices SIGMASCOPE GOLD B and SIGMASCOPE GOLD C, you can check the authenticity of gold anytime โ€“ quickly and accurately. Using conductivity, these gold testers reliably show if inclusions of foreign materials like tungsten are present. The authenticity testing of gold is therefore non-destructive and causes no loss of material or value.

The SIGMASCOPE GOLD B was developed especially for analyzing gold bullion. While this handheld device can measure bars up to 17mm thick (from approx. 1 oz to approx. 1 kg), its variable penetration depth settings also make the testing of thinner bars possible. 

The SIGMASCOPE GOLD C is a handheld device for checking the authenticity of gold coins and thin bars (up to approx. 100 g). Whether itโ€™s Krugerrands, ducats, coin gold or fine gold โ€“ with this easy-to-use gold tester, you know immediately whether that which glitters is really gold.
