Instrument introduction

EDX 860D, a specialized precious metals tester, is capable of measuring inner walls of the circular samples as well as conducting common planar testing.
Its features are: 
Small and light;
Elegant and attractive ;
Manual lift platform for measuring samples of different sizes;
Simple ways of sample holding;
Convenient to change the collimators;
The diameter of the collimator is as small as 1.5mm, making it possible to measure the micro area;
Bottom lightening structure
Large window proportional counter, meeting the requirements of different applications;
Large sample chamber for measuring large samples;
Laser positioning of CCD permitting visualized positioning of samples;
Good radiation shielding capability protects the operators.

Performance characteristics

Large power X-ray tube 
Super large window proportional counter
Small and elegant
Large window proportional counter, meeting the requirements of different applications;
Manual lift platform for measuring circular samples of different sizes;
Small collimator enables the test of micro area
Laser positioning CCD positions the test spot visually and accurately. The laser automatically stops when the measurement starts, which helps taking clearer pictures.
Good radiation shielding capability guarantees the safety of the operators
