PRECIOUS METALS AND JEWELRY

Safe Analysis, value determination and authenticity testing

Is it real gold?

Authenticating jewelry and precious metals

Fine jewelry is not only for decoration and embellishment. Rather, it represents a lasting investment. When buying and selling, trust is good, but it can cost you dearly. Therefore: Com the safe side when checking the authenticity of jewelry and precious metals, gold bars and gold coins. The measuring instruments are tailor-made for examinations in the laboratory as

Available with front-opening

or top-opening measurement chamber door, with Si-PIN detector or SDD.

In addition to the XRF

instrument, the scope of deliv- ery includes a PC incl. WinFTM® software as well as keyboard and mouse.

Start / stop

buttons allow measurement to be started directly on the instru- ment. Focus button for optimum sharpness and image results No external training required due to type-approved full protec- tion device.

Use of eddy current measurement method

Coin trade and coin authenticity testing

This is achieved by using the phase-sensitive eddy current method. The actual measurement signal is gen- erated directly in the coating. The probe therefore does not have to be placed directly on the metallic layer. This means that conductivity can also be determined under non-conductive cover layers such as plastic packaging The penetration depth of the eddy currents can be select- ed to match the thickness of the measured object. sive and professional service as we do on the quality of need in terms of professional quality management.
