All VRAY jewelry testing machine models feature powerful 50W micro-focused X-ray tubes and T-shaped radiators for safe heat dissipation, eliminating external cooling. Integrated computers ensure intuitive operation. Our solutions guarantee rapid, reliable, and exceptionally accurate precious metal testing for all professional applications.
Advanced X-ray Tubes: Our machines utilize powerful 50W (50 kV, 1mA) micro-focused tungsten X-ray tubes. The VR-T7 even features a beryllium window tube for enhanced precision. These tubes efficiently generate the primary X-ray beam necessary for elemental excitation.
High-Performance Detectors: VRAY employs various high-quality detectors:
Gas Proportional Detector: Found in models like the VR-X3, providing reliable accuracy for common gold testing.
Customized Si-Pin Detectors: Present in VR-S6 and VR-H5, often sourced from the USA, offering enhanced sensitivity and 0.03% accuracy for 9999 gold.
High Sensitivity SDD Detector: Featured in the top-tier VR-T7, enabling exceptional 0.01% accuracy for 9999 gold.
Precise Collimation: A ϕ2.5mm collimator (or ϕ1.5mm in VR-T7) focuses the X-ray beam, ensuring accurate targeting of the sample.
Integrated Computing & Software: All desktop models include powerful built-in industrial computers (e.g., Intel i5, Windows 11) for seamless operation, data processing, and result display via touchscreens.
Efficient Heat Management: A dedicated T-shaped radiator system efficiently dissipates heat, eliminating the need for external cooling and ensuring stable, continuous operation while enhancing safety.
Enhanced Features (Select Models): The VR-T7 boasts a manual XY platform for precise sample positioning and a 5-megapixel CMOS camera with 40x-160x magnification for detailed visual inspection. The VR-H5 offers unique portability with an 8-hour intelligent battery and broad operating temperature range (-20℃～50℃).

Remote guidance
Ensuring the safe and accurate performance of your Jewelry Testing Machine requires strict adherence to operational guidelines and an awareness of potential hazards.
Power on the machine and open the software.
Preheat the instrument for 10 minutes.
Calibrate the instrument daily with the provided calibration sample upon its first use.
Place the sample in the detection area, then strictly close the protective door before pressing "start" to test.
Wait for the result; preliminary analysis displays in 3 seconds, complete results in 30 seconds. You can then print an A4 or Bluetooth report, or save it.
It's recommended to use a regulated power supply or UPS to prevent damage from voltage fluctuations.
Keep the working environment dry, clean, and well-ventilated, avoiding high temperature and high humidity.
Always follow the operation manual and manufacturer's training guidelines; do not modify parameter settings privately.
Starting a test when the protective door is not tightly closed can cause X-ray leakage and radiation damage to the operator.
Forcibly cutting power or frequently turning the machine on/off can damage the X-ray tube, high-voltage module, or hard disk, leading to system crashes.
Operating in humid, hot, or dusty environments can cause overheating, mainboard dampness, and detector malfunction or short-circuit.
Unauthorized modification of software parameters or calibration data may cause data distortion, potentially requiring the software to be returned to the factory for recalibration.
Touching the detector window with sharp objects or fingers will damage the detector film, resulting in extremely high maintenance costs.
Moving the sample or opening the door during a test can cause the sample position to shift, leading to test failure and X-ray exposure.
