Gold Testing Machine XDAL-237
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.
Design
- 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 μm (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
