Karat Meter

Karatmeter G-series is bench-top fast, precise & non-destructive unit for accurate elemental analysis. Fixed sample position precisely & swiftly determines the percentage by weight (or Karat) in a solid piece of jewellery, precious coins or any other piece of noble metal making use of X-ray assay technique. It successfully determines the elemental composition of Gold alloys, Platinum group metals & Silver alloys. The analysis of bulk material & layer thickness is non-contact and non-destructive without any requirement for sample preparation. With additional calibration module, it can be even use for special coating thickness applications and plating chemical analysis.

Who Benefits

Karatmeter G-series metal spectrometer is ideal for labs and production lines, particularly where users have:

• Limited bench space
• Budget limitations
• A preference for bottom-up operation with optional motorized z-focusing
• The need to position smaller samples quickly and easily for fast output 

The two most distinctive features of the G-series are precision video imaging, and bottom-up measurement using a fixed plate or optional motorized z-axis with laser-based auto-focus. An optional  manual X-Y stage with 1.5X1.5 travel facilitates easy positioning of small and large parts. These features are unique as compared with other suppliers.  

Configuration 

The standard configuration includes a dual collimator, a camera with a fixed focal distance, solid-state silicon PIN detector, and a long-life X-ray fluorescence tube. As with all existing or new models, components can be upgraded to include multiple collimators, a variable focal depth camera or high resolution SDD/FSDD detector. 

Principle :  Energy dispersive (ED-XRF) X-ray fluorescence spectrometer to measure precious metals and alloys.

Design : Universal robust bottom-up geometry to measure samples with fast output. The front large door opening allows easy sample handling for positioning andmeasurement. The sample is visible through protective door window during measurement.

Electrical Conditions:  Operates on standard external AC adaptor works with mains power supply between 110-240VAC, 50/60Hz, 100W.

External Conditions : 

•  Operating 0-40 degree C
• Storage/transportation 0 - 50 degree C
• Relative Humidity < 95%

Sample Handling : Fixed sample plate, optional motorized z-axiswith laser based auto-focus and optional manual x-y position stage.

Sample Image :High resolution CCD color video microscope for optical image of sample position with cross-hair and spot size on calibrated scale. Adjustable illumination and magnification upto 40x.

Interface :  Standard single USB interface with external laptop/desktop WIN based computer.

Software :  XralizeR special software package pre-calibrated for major precious metals and alloys with help driven menu and customized report generation formats.

Approvals : CE design approval, AERB approval for radiation safety, IP40 dust & moisture protection, DIN ISO 3497 & 23345 and ASTM B 568 approvals for standard XRF measuring techniques.
