With this pen, you can check the authenticity of gold jewelry of any shape and color (including platinum), as well as the authenticity of coins and gold bars. Within a few seconds, you will know the carat weight of the gold object and whether the precious metal matches the specified standard. The sophisticated measuring system of this new device allows you to determine the amount of gold in almost any gold object. And all this is possible without special acids, impractical measuring equipment or expensive X-ray fluorescence instruments. The settings of the device are quite simple, which makes it ideal for private and commercial users. Simply place the sample in the CaratScreenPen sensor box and touch the pencil to any point on the surface of the object to be tested. After a few seconds, the display will show the number of carats and the percentage of gold content. This machine guarantees a large number of samples in a short time - no other metal testing machine can work so fast.
