About XRF spectrometers
ElvaX Jewelry Lab
ElvaX Jewelry Lab was designed for high-accuracy analysis of precious metals and jewelry. Measurement process takes only several seconds; result is shown in % and karats. ElvaX Jewelry Lab is also capable of detecting coatings and nonstandard alloys. The instrument can be operated both using the embedded hi-res display and using ElvaX software installed on a PC. The integrated CCD camera allows you to target the required spot of the analyzed sample. Automatic collimator change allows you to select the required measurement spot diameter. ElvaX Jewelry Lab has integrated high-accuracy scales and an integrated printer, which allows you to print out analytical certificates containing chemical composition, weight, and even price. A rechargeable Li-ion battery allows for analysis in the field.
Fields of application
EllvaX Jewelry Lab is used for qualitative and quantitative analysis of precious metals. Analysis accuracy is at least 0,1%.
- Jewelry analysis
- Precious metals refining industry
- Precious metals assay
User advantagesHigh speed and accuracyIntuitive interface. Autonomous operations as well as connected to a PCCoatings detectionCompact. Doesn’t occupy much space on a counter. Ergonomic design with a LED lighting looks very good in a jewelry shop. Transparent lid – sample is always seen by customer Customer display – sample’s weight and chemical composition are seen by customer during measurementAdditional customer screen can be connected to ElvaX Jewelry LabUSB port for data export
