Ultrasonic Device – For Testing Real or Fake Gold, Silver bars / Coins
Look what we got here? This is a simple ultrasonic device that we can use to test for real or fake gold. Similarly it can be used to test real or fake silver.
Many of my regulars who have bought precious metals from me over time understand that my gold, silver bars comes in their original packaging. Those that are minted with serial numbers and certificates can give a sense of security. For those bars and coins that have no serial number nor certificate, I have bought this new ultrasonic device to give them another layer of authenticity.
The sound velocity for pure gold should be 3200 meters / second (or 0.130 Inch/µSecond) The sound velocity for pure silver should be 3600 meters / second (or 0.140 Inch/µSecond)
Remember, please only buy gold and silver bars / coins from reputable merchants like www.goldsilvercity.com.sg For more updates and useful articles, please do LIKE http://www.facebook.com/goldsilvercitysg
For any clients who wishes to buy gold or silver, you can request for a testing. I will bring the ultrasonic device when I deliver the gold, silver, bars and coins to your doorstep. Have fun stacking precious metals!
