Gold Karat Meter - Silver Alloy Karat Meter and Carat Meter for Gold

Our Products Karat Meter and Gold Testing Machines Goldscope

Goldscope

"Designed and developed in accordance with international industrial standards for Retail Jewellery Stores , Goldscope is basically a type of an X-ray fluorescence measuring instrument with SI- PIN Detector optimised for non-destructive analysis of the gold and silver alloys along with detection of Powder such as Iridium, Ruthenium . It can easily analyse the Gold and indicate values in carat or weight%. Goldscope is a Cost-effective and compact entry-level X-Ray Fluorescence (XRF) Measuring Instrument for fast and non-destructive Analysis of Gold and Silver Alloys"

Software Used : WinFTM®
Design Standards : DIN ISO 3497 and ASTM B 568

Design

The unit is compactly designed as user-friendly bench-top instrument. It is light in weight and require less space.

The door of the instrument opens in the front not upwards thus saving more space.

The lower chamber possess detector assembly and X-ray source which helps in easy positioning of sample in the instrument.

The measuring direction under the sampling tray is supported by a transparent window

Its precise measuring spot adjustment is the result of the integrated video-microscope with zoom and cross-hairs, which simplifies sample placement.

The system is operated through powerful and user-friendly WinFTM® software for the entire operation and evaluation of measurements as well as the clear presentation of data using PC.
