X-Ray Fluorescence Measuring Instruments
Optimized for Fast, Cost-effective and Non-destructive
Analysis of Jewelry, Coins and Precious Metals
The GOLDSCOPE SD 510 offers the smallest footprint, because the measurement chamber
door does not open upwards, but towards the front. Thus, you can place a notebook for
operation onto the instrument, which saves space.
The X-ray fluorescence measuring instruments of the GOLDSCOPE SD series are optimized
for fast, cost-effective and non-destructive analysis of jewelry, coins and precious metals.
Furthermore, the instruments are well suited for determining the thickness of gold coatings
on sterling silver and rhodium coatings on gold alloys.
The GOLDSCOPE SD series comprises four different instruments to fulfill the specific
demands from the fast purchase and sale of gold up to the high-precision analysis of
precious metals.
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
Outstanding accuracy and long-term stability are characteristics of all X-RAY systems from
FISCHER. The necessity of recalibration is considerably reduced, saving time and effort.
