ElvaX Jewelry Lab

ElvaX Jewelry Lab is aimed on high-accuracy analysis of jewelry and precious metals. Measurement process only takes several seconds. The result is shown in both percent share and karats. ElvaX Jewelry Lab is also capable of detecting coatings and nonstandard alloys. This instrument can be operated either using the embedded computer with the high-resolution touchscreen display, or using a PC with ElvaX™ software installed. The integrated CCD camera makes it possible to target the required spot of the sample undergoing analysis. Automatic collimator changer allows you to select the required measurement spot diameter. ElvaX Jewelry Lab has integrated high accuracy scales and an integrated printer, which allows the user to print out analytical certificates containing chemical composition, weight and even price. An integrated rechargeable Li-ion battery allows the analysis in the field. ElvaX Jewelry Lab is a perfect benchtop gold and silver testing machine which allows you to define gold and silver purity and measure gold assay.

Designed for high-accuracy analysis of precious metals and jewelry


  • High speed and accuracy
  • Intuitive interface
  • Autonomous operation as well as connected to a PC
  • Coatings detection
  • Compact, doesn’t take much space on a desk or a counter
  • Ergonomic design with a LED lighting looks very nice in a jewelry shop
  • Leaded glass to keep analyzed items always in sight
  • Customer display – sample’s weight and chemical composition are seen by customer during measurement

X-ray fluorescence analysis surpasses the rest of analytical methods in terms of speed, accuracy, and simplicity. It’s a non-destructive method, in which analysis is targeted at the spot of interest. The diameter of an analytical spot can be easily changed.
