 ElvaX Jewelry Lab in precious metals analysis - Application note
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%.
