MagneticScreenScale
Another complementary method for measuring the bars and coins is to determine the, so-called magnetic susceptibility properties, with the MagneticScreenScale. This method can check through blisters and packaging up to a certain thickness and determine whether the applied material has the correct magnetic behaviour (para- or diamagnetic). The magnetic balance is a purely qualitative process and a quantitative determination of the gold content is not possible.
So you can check the presence of a potential foreign metal inclusion - that's why we often refer to the magnetic balance as a “tungsten detector”. Because a gold bar, as a so-called diamagnet, displaces a magnetic field and counteracts it - this creates pressure on the measuring head and a positive value is displayed. If you put on a supposedly real fine gold bar and a negative value appears, something is usually “fishy”.
Please note that if the material, that is being counterfeited, is also a diamagnet, a positive value will also appear and detection of the counterfeit with the magnetic balance alone is impossible.
Magnetic Scale
Precision magnetic scale - MagneticScreenScale
The MagneticScreenScale lets you detect such forgings quickly and with certainty. The scales' strong magnetic field penetrates the ingot's or coin's core deeply without destroying it. Tungsten can be discovered until 3 mm below the golden surface! The biggest advantage of the magnetic scales is that it detects tungsten occlusions in fine gold (99.99 % gold). The information here is always unambiguous and tungsten inclusions are still detected under a gold layer of up to 3 mm with complete reliability. In comparison, an expensive XRF-device can only pervade 0.010 mm into gold. That means that the magnetic scales measure about 300 times more deeply into the metal. That's why the magnetic scales are ideal for testing the authenticity of investment gold (ingots, coins, etc.) in a high troughput. Thanks to its accumulator, the scales can be run in places without mains power and is a perfect assistant when purchasing investment gold.
But also many kinds of forging silver, as well as forgings of platinum or palladium can be discovered. Particularly convenient: the testing samples don't need to be taken out of its plastic blisters, plastic films or capsules (when they are not extraordinarily thick). That means that also small investment ingots that are firmly welded can be examined fast and with high certainty. Even jewellery can be tested regarding the often used tungsten carbide cores. You'll obtain the magnetic scales in a noble and robust aluminium carry case. Purchase the original from us - the proven and reliable solution to testing gold.
Properties:
• quick authenticity test of gold and silver
• can also measure through capsules, blisters and plastic films
• about 3 mm penetration depth into gold and silver
• The MagneticScreenScale - the fastest tungsten detector
• Measure objects of up to 250 g
• Tungsten forgings are dangerous! Tungsten has the same specific density as gold and is therefore the perfect forging material for gold ingots and -coins.
