EDX 880, a specialized precious metals tester, is capable of measuring inner walls of the jewelries and other irregular samples.

Performance characteristics

Large power X-ray tube 
Super large window proportional counter 
Curved design, elegant and eye-catching
Large sample chamber houses large samples
Multiple sample holding ways (universal sample clamp, sample plate, plasticine), offering common tests, inner wall tests and irregular samples tests 
Manual lift platform offers tests of samples of different thicknesses 
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
The measurement can be observed through the transparent cover.
