Ultrasonic measuring instrument for checking the authenticity of gold bars and coins.

Features

• You can use the TN-GOLD to determine whether gold or silver bars and coins are genuine or whether they contain a core of a different material
• The instrument measures the thickness of gold bars and gold coins using ultrasound
• Process: Ultrasound waves are directed onto the test object using a sensor. The waves penetrate the test object, are then reflected from a surface opposite the object and then picked up again by the sensor. The measurement determined by this process will be compared with the material thickness as measured by a traditional calliper gauge. On the basis of the measurement given,  false cores (Figure: grey) for example, those made of tungsten, lead, etc. can be easily identified, as the ultrasound reacts differently, compared with pure gold
• Selectable measuring units: mm, inch
• Using the SAUTER SSG software (included), you can determine whether the test item is genuine or contains a false core – and you can be very confident of the result
• Known additions in tested gold items – e.g. copper or silver – are compensated by the software
• In addition, the software determines the value of the gold item. The price of gold is polled on line continuously
• It is the only test process which measures right through the whole bar or the whole coin without interference and thereby guarantees the highest level of certainty
• Internal memory for up to 20 files (with up to 100 values per file)
• Base plate for adjustment incorporated
• Data interface USB, standard
• Delivered in a robust carrying case
