Fischer measurement Technologies (India) Pvt. Ltd.



GOLDSCOPE SD 515 is a compact entry-level X-ray fluorescence measuring instrument for fast and non-destructive analysis and coating thickness measurement of gold and silver alloys.

It is used for the non-destructive analysis of jewellery, coins, and precious metals. The machine is ideally used for the analysis of precious metals and their alloys for composition purity and coating thickness. The machine is used for measuring simultaneously up to 24 elements in the range of chlorine (17) to uranium(92).
The silicone PIN detector provides good detection sensitivity with high accuracy. The device works with stability and accuracy with a considerable reduction in recalibration thus saving time as well as efforts.


  • An ergonomically engineered user-friendly device in a compact size with longer service life
  • It is light in weight and requires less space for installation.
  • The door of the measurement chamber does not open upwards, but towards the front which allows placing notebook for operation onto the instrument thus saves even more space.
  • The X-ray source and detector assembly is located in the instrument's lower chamber for quick and easy sample positioning. It is also fitted with the integrated video-microscope with zoom and cross-hairs that simplifies sample placement and also allows a precise measuring spot adjustment.
  • The system runs on powerful and user-friendly WinFTM® software which ensure smooth operations and evaluation of measurements as well as the clear presentation of measurement data.



  • Compact design, efficient, lightweight instrument (appr. 25 kg, 55 lb) and small footprint
  • Designed particularly for analysis of gold alloy at reasonable prices
  • Equipped with a SI-PIN detector that is also suitable for more complex analyses with other elements
  • The machine has been designed for quick and sampling position


Typical fields of applications:

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