XAN SDD XDV-SDD Gold Testing Machine For Hallmarking Centres

The high-end measurement system Fischerscope X-Ray XAN SDD was developed specifically for non destructive, high precision analysis of thin gold and precious metal coatings. Gold testing machine in hallmarking centres: XDV-SDD is engineered under the firm direction of expert quality controllers. These are basically X-ray fluorescence measuring instrument with a programmable XY-stage and Z-Axis for Automated Measurements of very thin coatings and for trace analysis. These are extensively used as an energy-dispersive X-ray fluorescence measuring instrument for the measurement and analysis of very thin coatings or small concentrations in the trace analysis.
