Watches Coating Thickness Measurement Instrument XDAL

Watches Coating machine XDAL237 is engineered to use as X-ray fluorescence measuring instrument with a modern programmable XY-stage and Z-axis for automated measurements. Our Watches Coating Thickness device is ideal to test the thin coatings in Gold Hallmarking, Manufacturing and Assaying Centres. They are extensively used for non-destructive measurements and analysing very thin coatings.


Uniquely designed with high-precision, programmable XY-stage and an electrically.

User-friendly bench-top instruments for sample stage moves into the loading position automatically, when the protective hood is opened.

Compact, robust and highly stable with laser pointer works as a positioning aid and help fast alignment of the sample to be measured.

Operated through the powerful WinFTM® software designed as per German regulations Deutsche Rontgenverordnung-rov". Its whole process, evaluation of measurements and clear presentation of measurement data is conducted on a PC through software.

Application Areas

Study of very thin coatings of 0.1m (0.004 mils)

Measurements of functional coatings in the electronics as well as semiconductor industries
