Product Description


  1. Goldscope SD Pro:

Cost-effective entry-level X-Ray Fluorescence Measuring Instrument for fast and non-destructive Analysis and Coating Thickness Measurement of Gold and Silver Alloys

The Goldscope SD Pro  is the cost-effective entry-level X-ray fluorescence measuring instrument for non-destructive analysis of jewelry, coins and precious metals.

It is particularly suited for the analysis of precious metals and their alloys in composition and coating thickness. Up to 24 elements can be determined simultaneously.

Typical fields of application are the analysis of:

  • Jewelry, precious metals and dental alloys
  • Yellow and white gold
  • Platinum and silver
  • Rhodium
  • Alloys and coatings
  • Multi layer coatings

Outstanding accuracy and long-term stability are characteristics of all Goldscope systems. The necessity of recalibration is dramatically reduced, saving time and effort.

The modern silicon PIN detector achieves high accuracy and good detection sensitivity.

The fundamental parameter method by FISCHER allows for the analysis of solid and liquid specimens as well as coating systems without calibration.
