Precious Metal Detectors
It’s no secret that every day there are more counterfeit bank ingots of precious metals and jewels. Today, there is a simple and fairly quick way to detect precious metals. Perhaps with a high degree of accuracy to determine the identity of the metal to a group of items and learn its standard . To do this, you need to buy the precious metal detectors , which minimize the risk of buying a fake.
The components of the detector
The detector is non-destructive rapid control of precious metals and jewelry surface of the material on the electrochemical potential.
Sale of detectors is performed in assembled form , its components design are:
basic measuring unit
remote power supply unit
probe with built capsule that contains a special solution .
qualitative characteristics
Precious metal detectors are characterized by huge functionality , of which there are:
–Very high reliability of the system – its accuracy is close hundred percent. Accuracy is ensured by the use of instruments and methods , which are based on different physical, chemical and physical principles. Therefore , proper use of the detector eliminates the chance of missing a fake ingot.
–Economic efficiency. Precious metal detectors are able to pay for itself , immediately after the discovery of a fake gold ingot weighing one kilogram.
The measurement process
Measurement of precious metal detector is performed by touching the tip of the probe to the surface of the material being examined , until the on-screen detector final result of the measurement. From the value of the potentials that are displayed on the monitor of the detector , the Directory or by using a computer program, you can determine which alloy is tested , and precious metals are identified in the sample .
It is important that the touch area is not less than one square millimeter , so complicated research jewelry made in the form of chains . Also, the surface is studied , should be free from dust and dirt.
sphere of application
Precious metal detectors used in banks in order to determine the authenticity of bullion coins made of precious metals , to quickly detect forgeries , characterized by the composition of the material from the original products. Precious metal detectors are also used in the retail and wholesale trade antiques and jewelry, and to work in the pawn shops to assess the quality of jewelry handed .
Irreplaceable precious metal detectors in expert forensic laboratories to perform rapid testing of metal and alloy used in manufacturing. Precious metal detectors are used for customs control of the inspection in the stationary and in the field. Sale of detectors and the methodology used necessarily certified . To pawn shops and retailers can use a modification of the detector, programmed to perform control only products from precious metals
