Product Description
Quantum the well-known name in jewellery industry since over 2 decades introduced new series in precious measurement with latest hardware technology, intuitive software package, simplicity in operation at affordable cost. The complete spectrometer is controlled by external PC using standard USB interface. The entire operation and measurement evaluation is performed by PC using powerful XralizeR software package.
The combined force of technology and experience innovate this latest product for fast, non-destructive and accurate measurements of jewellery articles and precious alloys. The unit is most favourable for jewellery showrooms, bullion merchants, hallmarking & assaying, refineries, gold manufacturers, pawn shops, bank valuation, silver articles, dental alloys and many more. With additional calibration module, it can even use for coating thickness and plating chemical analysis.
Intuitive User Interface
- Simple compact design for daily testing functions
- Closed couple top geometry for increased precision & efficiency
- Advanced functionality access to power users
- Unlimited access for creating new applications
- Easy data storage/recall and transfer facility
- Customizable keys for quick analysis and reports
- Quick plug-and-play access with diagnostic mode
Karatmeter is a fast, precise and non-destructive tool for accurate analysis of bulk material and layer thickness. The unit precisely and swiftly determines the percentage by weight (or karat) in a solid piece of jewellery, precision coins or any other piece of noble metal making use of XRF assay technique. It successfully determines the elemental composition of all gold alloys, platinum group metals, silver and dental alloys. The analysis of bulk material and layers is non-contact, non-destructive method without any requirement of sample preparation.
