Gold Testing Machine

Measurement Performance

With just a single button press, the device provides results including elemental composition, gold purity percentage, and karat value. Equipped with an X-ray shielding system, it ensures absolute safety for the user.

Sample observation is assisted by a high-quality CCD video camera. The analysis is non-contact and non-destructive, delivering results within 60 seconds to 2 minutes. Extremely user-friendly—simply position the sample to begin.

Capable of detecting up to 20 elements: Au, Ag, Cu, Zn, Ni, Pd, Cd, Rh, Ru, Pt, etc.
Harmful metals such as lead (Pb) and cadmium (Cd), which are prohibited under Circular 22, can also be detected.

The SDD detector enables detection of rare elements such as Iridium (Ir), Osmium (Os), Ruthenium (Ru), and Tungsten (W).

Analysis Software

• Simultaneous analysis of up to 8 elements
• Supports detection of up to 20 elements
• Statistical functions with average value and standard deviation
• User calibration capability

Sample Positioning

The machine allows adjustable sample positioning based on the size and location of the gold item being tested. The Cube series supports automatic XYZ-axis adjustment for precise and flexible sample alignment.

Compact Design

Thanks to its smart, space-saving design, the device is compact enough to fit seamlessly into any setting—from small jewelry showrooms to full-scale business environments.

Detector Types

Current models commonly use two types of detectors:

• Silicon Drift Detector (SDD): Offers the highest sensitivity and accuracy available today.
• Silicon Pin Detector (Si-Pin): Detects many elements such as Au, Pt, Rh, Cu, Zn, Ag, Co, Ru, Pd, Ni, Cr, Mo, Ir, Bi… However, it is less effective at detecting Osmium (Os), which is relevant in Vietnam's gold market. Si-Pin also has slightly slower processing speed compared to SDD.

Coating Thickness Measurement

This feature is especially beneficial in the plating and electronics industries.
