Gold testing machine in hallmarking centres: XDAL237 is engineered under the firm direction of experienced quality controllers. These are widely used as X-ray fluorescence measuring instrument with a programmable XY-stage and Z-axis for automated measurements of thin coatings in Gold Hallmarking, Assaying and Manufacturing Centres.These are widely used for non-destructive measurements and analysing very thin coatings.

  • These are uniquely designed and developed with high-precision, programmable XY-stage and an electrically.
  • These are user-friendly bench-top instruments acclaimed for sample stage moves into the loading position automatically, when the protective hood is opened.
  • These are compact sized, robust designed and ensure longer stability. Its laser pointer works as a positioning aid and supports the quick alignment of the sample to be measured.
  • These are operated through the powerful and user-friendly WinFTM® software and designed as per German regulations Deutsche Rontgenverordnung-rov". Its entire operation and evaluation of measurements as well as the clear presentation of measurement data is performed on a PC through software.


Typical areas of application are
  • Analysis of very thin coatings of 0.1 ¼m (0.004 mils)
  • Measurements of functional coatings in the electronics and semiconductor industries
  • Determination of complex multi-coating systems
  • Automated measurements, e.g., in quality control
  • Determination of the lead content in solder


General Specification
