Electronic Gold Testing Machine for Hallmarking Centres : XAN-FD

Gold testing machine in hallmarking centres: XAN-FD is a fast and non-destructive coating thickness measurement and material analysis. These are compact in size and widely applicable as an energy-dispersive X-ray fluorescence measuring instrument.

Our machines are extensively used for non-destructive thickness measurements and material analysis. These are fitted with electrically changeable apertures and primary filters and modern silicon PIN detector for excellent detection sensitivity and high accuracy. These can be used for coating systems as well as solid and liquid Samples can be analyzed standard-free. Besides, these can easily measure up to 24 elements in a Range from aluminum (13) to uranium (92) simultaneously.

Our machines are acclaimed for their long term stability, excellent accuracy, long term stability and ergonomic design. These are very easy to operate and acclaimed for fast calculation and quick data presentation. These are well suited for measuring and analyzing thin coatings, even with very complex compositions or small concentrations.

Design

We provide user friendly bench-top instruments. These are available in two different range including XAN-FD and XAN 152 and these differ in support stage and the housing size

These are fitted with the X-ray source and semiconductor detector assembly is located in the XAN 120 lower chamber, so that the measuring direction is from underneath the sample.

These are ideal to measure range of up to 22 mm. straightened with the integrated video-microscope with crosshairs and up to 184x zoom factor simplifies sample placement, these devices are very easy to install, operate and maintain

These are operated through powerful WinFTM® 2 FISCHERSCOPE® X-RAY XAN®-FD, XAN® 152 -FD, XAN® XAN® 152 software, which make these very user friendly and easy to use.

Typical areas of application are:

Measurement of functional coatings in the electronics and semiconductor industries

Analysis of alloys in the jewellery and watch industries

Research in universities and in the industries
