The VRAY VR-H5 Gold Tester Gun works using X-ray Fluorescence (XRF) technology. It emits X-rays onto a sample, analyzing the unique fluorescent signals to precisely identify elemental composition and purity (e.g., gold karatage) non-destructively in just 30 seconds.
It prevents fraud by quickly verifying gold purity, enhances transaction efficiency with rapid results, and expands testing capabilities through its portable, on-site design. It performs multi-material analysis beyond gold, serving diverse industries like scrap recycling. Long battery life and efficient cooling ensure operational continuity, while its robust design allows reliable use in extreme temperatures, broadening its application scope.
When choosing a gold tester, you'll encounter two main types: the Gold Tester Gun (handheld) and the Benchtop Gold Tester Machine (desktop). Here's a comparison to guide your decision:
Aspect | Gold Tester Gun (Handheld) | Benchtop Gold Tester Machine (Desktop) |
Portability | High (battery, field-ready). | Low (fixed, AC power). |
Accuracy | Good (e.g., VRAY VR-H5 0.03%). | Higher (e.g., 0.01%, advanced). |
Cost | Often higher (portability premium). | Varies, potentially more economical. |
Operation | Point-and-shoot, flexible. | Sample placed in chamber, standardized. |
Use Case | Mobile buying, pawn shops, field. | Labs, refineries, production. |
Safety | Operator diligence. | Superior built-in shielding. |
Setup | Quick, immediate use. | More involved setup. |
Using a gold tester gun like the VRAY VR-H5 is straightforward, but remember, safety is crucial as it uses X-rays. Always follow these operational steps and essential safety precautions for effective and secure testing.
1. Power On: Ensure the device is charged. Turn it on and allow any necessary warm-up.
2. Position Sample: Point the test window directly at the sample's clean, flat surface.
3. Select Mode: Use the 4.3" touch screen to choose the appropriate test mode.
4. Initiate Scan: Press the test button to begin the 30-second analysis.
5. View Results: See precise gold purity (e.g., 18K, 24K) and elemental content displayed on screen.
6. Manage Data: Save results; transfer data via USB or Bluetooth to a computer for records.
This device uses X-rays, so radiation safety is paramount. Never aim the test window at yourself or anyone else, as X-ray exposure can be harmful. Always keep all body parts, especially fingers, completely clear of the test window during operation. Use the device strictly as intended and according to the manufacturer's manual. To minimize exposure, don't extend test times beyond what's necessary for analysis. Only trained and authorized personnel should operate the device. Always store the device in a secure, designated area away from untrained individuals. For your safety and the device's integrity, never attempt to open it or perform maintenance/repairs yourself; only qualified technicians should handle these tasks.

The price range for the VRAY VR-H5 Gold Tester Gun is: $15,000 - $18,000.
When deciding to purchase the VR-H5, consider the following factors in addition to the initial price:
Accuracy Requirement: Is 0.03% accuracy sufficient for your specific business application (e.g., pawn shop vs. large refinery)?
Sample Types: Will you frequently test solid, liquid, or powder samples? The VR-H5 supports all.
Elemental Range: Beyond gold and silver, do you need to detect other precious metals or alloy elements, and would the optional excitation source target materials be beneficial?
Necessity of Portability: Do you frequently need to perform tests at different locations? If your use is primarily stationary, a desktop XRF might offer better value or even higher ultimate precision in some aspects.
Operating Environment: Do you operate in extreme temperatures or challenging field conditions where the wide temperature range (-20℃ to 50℃) is crucial?
Ease of Use & Training: How user-friendly is the device? Does VRAY offer operational training?
After-Sales Service & Calibration: What kind of technical support, warranty policy, and routine calibration services/costs does VRAY provide post-purchase? XRF devices require periodic calibration to maintain accuracy.
Data Management & Reporting: Do the device's data export and reporting features align with your business processes?
Accessories & Consumables: What are the replacement costs and availability of items like batteries and protective films?
Certifications & Compliance: Does the device meet relevant safety standards (e.g., CE, RoHS) and radiation safety regulations?
Considering these factors comprehensively will help you evaluate if the VR-H5 is the optimal investment for your business.
What did our happy clients say?
Just received my VRAY VR-H5 Gold Tester Gun and it's incredible! The 0.03% accuracy for 9999 gold is spot on, and the 30-second test time is a game-changer for my pawn shop. The 4.3" touch screen is super intuitive. It feels solid at 1.6kg, truly handheld. Highly recommend this for its precision and speed!
Bought the VRAY Gold Tester Gun last month for our jewelry recycling business. The multi-material analysis (solid/liquid/powder) is perfect for our diverse samples. It’s incredibly reliable even in our outdoor collection sites, thanks to its -20℃ to 50℃ operating range. The 8-hour battery life is fantastic. A must-have for serious buyers!
The VRAY VR-H5 is exactly what I needed for my mobile gold buying service. The USB/Bluetooth data transmission makes logging results effortless. Its 50KV/200μA excitation source ensures consistent, deep analysis. I'm especially impressed by the dedicated T-shaped radiator – no more waiting for cooling. This Gold Tester Gun is truly top-tier!
Our VRAY Gold Tester Gun arrived last week and has transformed our appraisal process. The 32GB memory is ample for all our data, and the custom Si-Pin detector delivers exceptional precision. We needed something robust and portable, and the VR-H5 fits perfectly. Its factory-direct price was unbeatable. Strongly recommended for any professional.
