Gold Karat Purity Analyzer

The Gold Karat Purity Analyzer is a sophisticated and highly accurate instrument designed for the rapid determination of gold purity, karat value, and precious metal composition. Ideal for jewellery manufacturers, gold traders, assay laboratories, pawn shops, quality control departments, and precious metal testing facilities, the analyzer delivers fast and reliable results without damaging the sample.

Using advanced density measurement technology, the instrument determines gold purity and karat value in just two simple measurement steps. Unlike traditional testing methods, it does not require sulfuric acid solutions, touchstones, or destructive testing procedures. The tested item remains free from scratches, stains, or surface damage.

The analyzer is also capable of evaluating precious metal alloys with metallic plating thicknesses exceeding 30 microns and can be used as a general-purpose precision balance when required.

Applications

The Gold Karat Purity Analyzer is widely used in jewellery manufacturing, gold trading, precious metal refining, hallmarking laboratories, pawn shops, assay offices, quality control departments, and research laboratories. It provides a fast, reliable, and non-destructive solution for determining the purity and composition of gold and other precious metal alloys.

Limitations

• Not suitable for testing hollow samples.

• Not recommended for jewellery or specimens containing precious stones.

• Samples must be solid and fully immersed during density-based measurement.
