ElvaX Jewelry Lab

ElvaX Jewelry Lab is an advanced portable analyzer designed to enable a high-accuracy analysis of precious metals and jewelry. The measurement process takes just a few seconds. The outcome is displayed in percent share as well in karats.

The ElvaX Jewelry Lab analyzer can also detect non-standard alloys and coatings. Users can operate this instrument using the embedded computer with the high-resolution touchscreen display, or using a PC equipped with ElvaX™ software. The integrated CCD camera renders it possible to target the requisite spot of the sample under examination. An automatic collimator changer allows users to choose the necessary measurement spot diameter.

ElvaX Jewelry Lab has in-built high accuracy scales and an in-built printer, which permits users to take print outs of analytical certificates with details such as weight, chemical composition, and even price. An incorporated rechargeable Li-ion battery allows the examination to be carried out even in the field.


Analysis accuracy of jewelry and precious metals is better than 0.1%.


The entire measurement process takes just a few seconds.


High-accuracy scales, integrated computer, printer, and a rechargeable Li-ion battery


  • Compact, does not occupy a lot of space on a counter or a desk
  • Accuracy and high speed
  • Ergonomic design comprising a LED lighting that looks aesthetic in a jewelry shop
  • Autonomous operation as well as a PC connection
  • Coatings detection
  • Customer display—Sample’s chemical composition and weight can be seen by customers during the measurement
  • Intuitive interface
  • Leaded glass to keep the examined items in sight at all times

X-ray fluorescence analysis outshines the rest of analytical approaches with regards to accuracy, speed, and simplicity. It is a non-destructive technique, wherein the analysis is aimed at the spot of interest. An analytical spot’s diameter can be easily altered.
