Introduction
Congratulations on your purchase of the Goldanalytix CaratScreenPen. The Goldanalytix
CaratScreenPen is an easy-to-use and non-destructive testing device for the determination of
purity/carat number of gold alloy surfaces in jewellery and other precious metal objects.
Goldanalytix, established in 2012, is the leading provider of precious metal testing methods in
Germany. With the CaratScreenPen, we offer a testing device, which establishes the fine content
on the surface of gold jewellery, scrap gold and other auriferous material by means of an
electrochemical measurement method. In addition, it can be determined whether platinum,
palladium or rhodium-plated surfaces are present. The measurement method is based on the
fact the pen probe creates a so-called "galvanic cell" when in contact with the testing object on
the measuring surface and through the resulting voltage drop the corresponding carat number is
determined.
By the way: On our homepage at www.gold-analytix.com you will always find the latest version
of the instruction manual, so that you can keep up to date with new types of forgery and findings
around precious metal testing.
Important note on the optics of the probe pen and measuring surface: Every probe pen is
tested for quality in connection with the device, which leads to a slight discoloration of the
probe tip. This is not a lack in quality, but only a guarantee that your device was checked before
delivery. Due to technical production reasons, the measuring surface can show creasing, slight
scratches or traces which cannot be avoided. This does not affect the measurement in any way.
