Fast Non-destructive Precise karat / Percentage determination of precious metals using microspot X-ray tube technology |
|
Karatmeter – your tool for fast, non destructive and accurate karat measurement of precious metals and finished jewellery. |
|
Based on over 25-years of experience in non-destructive material analysis. Our fast, instant assay technique with X-rays, the Karatmeter will determine the precise percentage by weight (or karat) in a solid piece of jewellery, precious coin or any other piece of noble metal. Within a minute you can accurately determine the element composition of all gold alloys, platinum group metals and silver alloys. The analysis is non-contact, non-destructive and requires no sample preparation. Simply position the piece of interest with the aid of video microscope and start the measurement. Even untrained sales personal at jewellery showrooms can operate the system instantly.
Karatmeter - is an investment, that pays for itself in very short period of time with great accuracy. |
