It performs 30-second tests on solid, liquid, or powder samples, features a 5.7" retractable color touchscreen, a built-in 5-megapixel HD camera, and 32GB memory. Data transfer is flexible via USB or Bluetooth, and it operates across a wide temperature range of -20℃ to 50℃. The VR-M5 is priced between $15,000-$18,000.
VRAY VR-S6 (Mini Desktop): A compact yet powerful desktop solution delivering 0.03% accuracy for 9999 gold in just 30 seconds. Utilizing a Customized Si-Pin detector from the USA, it handles solid, liquid, and powder samples. The VR-S6 comes with an i5-1035G7 Windows 11 inbuilt computer and an 11.6" touchscreen for intuitive operation. This model is ideal for smaller spaces requiring high precision, priced at $12,000-$14,000.
VRAY VR-X3 (All-in-One Desktop, Entry-Level): This robust desktop tester provides reliable analysis with 0.1% accuracy for 999 gold in 50 seconds. It uses a gas proportional detector and is excellent for solids, detecting elements like Au, Ag, Cu, Pt, Pd, Ir, and Cd. Priced at $6,000-$7,000, the VR-X3 is a cost-effective solution for essential gold and silver testing.
Our solutions ensure fast, non-destructive fraud prevention, accurate appraisals, and stringent quality control, empowering businesses with reliable data.
VRAY's Gold & Silver Testing Machines, leveraging advanced X-ray Fluorescence (XRF) technology, provide indispensable accuracy and reliability for precious metal analysis. At its core, XRF operates by exciting the atoms within a sample with a targeted X-ray beam. Each excited element then emits unique secondary X-rays—its "fluorescence"—at specific energy levels. VRAY's commitment to precision is evident in our choice of high-precision detectors: the VR-M5 and VR-S6 models integrate Customized Si-Pin detectors from the USA, enabling exceptional accuracies of 0.05% and 0.03% for 9999 gold respectively, while the robust VR-X3 utilizes a reliable Gas proportional detector to achieve 0.1% accuracy for 999 gold. This advanced detection, coupled with intelligent software often running on inbuilt i5 computers and viewed on 11.6" touchscreens (VR-S6), allows VRAY machines to meticulously interpret signals and deliver precise elemental breakdowns and purity at remarkable speeds: 30 seconds for VR-M5 and VR-S6, and a swift 50 seconds for VR-X3. At the heart of this precision is a stable 50W micro-focused X-ray tube across all models. Crucially, VRAY's proprietary dedicated T-shaped radiator ensures superior heat dissipation, maintaining optimal operating temperatures and guaranteeing continuous, stable operation without cooling waits. This engineering choice directly enhances long-term measurement consistency and reliability. This non-destructive method is paramount as it safeguards the integrity of valuable items while offering laboratory-grade results, making VRAY machines a cornerstone for accurate and trustworthy precious metal assessment.
VRAY prioritizes design elements that enhance the accuracy and reliability of our Gold & Silver Testing Machines:
Detector Technology: The quality of the detector is crucial. VRAY's VR-M5 and VR-S6 models feature Customized Si-Pin detectors from the USA, known for their precision, contributing to accuracies of 0.05% and 0.03% for 9999 gold, respectively. Even our entry-level VR-X3, with its gas proportional detector, achieves a reliable 0.1% accuracy for 999 gold.
X-ray Tube Power and Stability: All VRAY machines utilize a powerful 50W micro-focused tungsten X-ray tube. This consistent and strong excitation source is vital for accurate fluorescence readings. The stable power supply and advanced cooling systems are key here.
Thermal Management (VRAY's T-shaped Radiator): A significant factor in long-term reliability is heat dissipation. VRAY's exclusive dedicated T-shaped radiator ensures our machines, from the portable VR-M5 to the desktop VR-S6 and VR-X3, can operate continuously without overheating or requiring cooling waits. This stability directly translates to consistent and reliable results over extended use.
Sample Preparation and Homogeneity: While VRAY machines are highly capable (e.g., VR-M5 and VR-S6 can test solids, liquids, and powders), the sample's surface must be clean, dry, and free from contaminants (like dirt, oil, or plating) to ensure the X-ray beam reaches the actual material. Non-homogeneous alloys can also affect readings, as XRF primarily analyzes the surface.
Calibration and Software Algorithms: Regular calibration with certified reference materials is vital for maintaining accuracy. VRAY machines integrate advanced algorithms, often controlled by powerful inbuilt computers (like the i5-1035G7 in VR-S6), to optimize spectral resolution and enhance measurement consistency and accuracy.
Environmental Control: Operating within specified temperature and humidity ranges (e.g., 10℃～35℃ for VR-S6, -20℃～50℃ for VR-M5) and in a dust-free environment helps preserve the sensitive internal components, contributing to consistent performance and longevity.
Aspect | How to Operate | Important Precautions |
Setup & Basic Use | 1. Connect to stable power (UPS recommended). Power on and allow warm-up. | • Operate within specified temperature (-20℃ to 50℃ for VR-M5, 10℃ to 35℃ for VR-S6) and humidity (40-70%) ranges. |
Results & Data | • View precise purity (e.g., 0.05% for VR-M5, 0.03% for VR-S6) and composition on screen. | • Regularly back up data. |
Maintenance & Safety | • Keep machine exterior and chamber clean. | • ONLY certified technicians perform internal repairs/maintenance. Never attempt DIY. |
Understanding the investment in a VRAY Gold & Silver Testing Machine goes beyond the initial price tag. Numerous factors contribute to the overall cost, ensuring you find the perfect balance between budget and performance.
Prioritize Accuracy vs. Budget: Determine your required level of accuracy (0.01%, 0.03%, 0.05%, 0.1%) and balance it with your budget. The VR-S6 offers excellent 0.03% accuracy, while the VR-X3 provides a cost-effective 0.1%.
Assess Portability Needs: If you require on-site testing, the lightweight and wide temperature range of the portable VR-M5 is ideal. For fixed locations, desktop models like VR-S6 or VR-X3 are more suitable.
Evaluate Sample Types & Speed: Consider if you need to test liquids or powders, as not all entry-level models (like VR-X3) support this. Match the test time (30s vs. 50s) to your operational volume.
Consider User Experience & Data Management: Decide if an integrated Windows 11 PC and large touchscreen (VR-S6) are preferable for your team, or if a more basic interface with flexible data transfer (VR-M5's USB/Bluetooth) suits your workflow.
Factor in Total Cost of Ownership: Look beyond the initial purchase price. VRAY's robust design (like the T-shaped radiator) aims to minimize long-term maintenance, but always consider shipping, potential installation, and calibration costs.
Leverage VRAY's Expertise: With 17 years of experience, VRAY can guide you to the model that perfectly fits your specific business needs, ensuring you invest in a reliable, high-performance solution.
