Vanta GX


The Vanta GX™ is an elegant and compact XRF benchtop analyzer for nondestructive testing on precious metals and carat identification, suitable if you buy gold, sell or produce jewelry, fabricate metal or recycle metal scrap.

It is designed for precious metal shops and showrooms but, thanks to its little weight (only 22 lbs – 10kg), the Vanta GX™ can be transported easily to wherever testing is needed giving accurate chemistry and karat results within seconds.

It allows to determine purity and fineness of precious metals for multi-elemental testing as economic alternative to traditional chemical tests for your silver, platinum, and PGM metals, impurities and, in additionally thanks to its innovative software, it can identify gold-plated objects also.

It is also available the optional battery for on-the-road testing during visits to customers and vendors.

The Vanta GX™ comes equipped with an integrated CMOS camera, which records sample images to memory along with analysis results. The data can be exported easily to spreadsheet format, and the memory can be accessed remotely when the GoldXpert is networked via its Windows CE operating system.

The Vanta GX™ is available in two versions:
– Features GX SDD for a Premium precious metal analysis
– Use GX PIN for an Affordable precious metal analysis
