Precious Metal Testing Set AuroTest - ATS 400/LFK The precious metal testing set Aurotest - ATS 400/LFK is a fast, highly reliable, non- destructive and very easy to use authenticity analysis system for investment gold coins and bars of common trade sizes and weights from 1 g up to 1000 g fineness (for flat bars up to 10 mm thickness). Beside gold and gold alloys for investement purposes it can test silver (including common silver bars and alloyed silver coins), platinum, palladium and rhodium. The ATS 400/LFK utilizes a measure- ment of the specific electrical conductivity of precious metals by eddy currents in order to evaluate the authenticity of fine gold bars and gold coins. This method is based on the an- alysis of the bulk metallic properties and not just on the analysis of a very thin superficial layer such as in X-Ray fluorescence analysis (XRFA). The ATS 400/LFK eddy current sensors can penetrate closed plastic blisters, foils and capsules with a thickness of up to 2 mm for proper testing the metal inside. Be- side a main sensor in the head of a electronic base unit there are also three external sen- sors with different diameters and penetrations depths available and part of the delivery. There is no need any more to send coins or bars to any assayer or precious metals refinery for authenticity testing. With the ATS 400/LFK you can check by yourself the fineness and homogeneity of your samples within seconds or find our possible fakes. Commonly used X-Ray fluorescence analysis instruments (X-RFA) for that purpose can not detect hidden precious metal imitates beyond a decorative layer thickness of about 10 to 20 micron. Gold coins and investment gold bars have been counterfeited over decades al- ready. Banks and precious metal dealers have been affected many times before by the purchases of fake gold, made of tungsten or mintable tungsten alloys such as (AgW85/CuW80/AgRe90) or other heavy metals. Since the year 2014 this kind of fraud became rampant also in the private gold investment market. For the ambitious precious metal investor the ATS 400/LFK makes an end on any doubts about possible fake bars and coins in his precious metals portfolio. For a bank, a large scale precious metal dealer, or an investment company this testing set offers the capability to check the genuiness and content of precious metal bars and coins for purchase, storage in custody or sales within seconds. All imitates can be easily and safely detected and excluded from dealing. The pricing of this testing set is still favourable in relation to the incurred financial loss, or possible loss in reputation by a single counterfeited investment gold bar when initially undetected.
