Following is the guide to XRF gold tester operation:
Power on the machine and open the software.
Preheat the instrument for 10 minutes.
Calibrate: Place the calibration sample for instrument calibration.
After calibration, place the sample in the detection area.
Close the machine cover and press the "Start" button to test.
Wait for the result. Generally, the preliminary analysis result will be displayed in 5 seconds, and the complete analysis result will be available in 30 seconds.
Print the report: When the test is completed, select the "Print" icon. You can choose to print an A4 report or use a Bluetooth thermal printer. Optionally, you can also save the report directly without printing it immediately.
For a more intuitive understanding of the usage process, please watch our XRF gold tester video tutorial.
VRAY's gold testers, within a price range of approximately $18,000 to $22,000. The pricing of gold testers is primarily influenced by their specific configuration factors:
Detector Type and Origin: The quality and origin of the detector, such as the customized SDD detector from USA mentioned for VR-T6, can impact cost.
Collimator Size: Differences in collimator size (e.g., 1.5mm for VR-T7 versus 0.8mm for VR-T6) suggest varying levels of precision or application focus, affecting the price.
Integrated Imaging and Optics: Features like a high-resolution camera and magnification capabilities (e.g., 5-million-pixel camera and 40x-150x magnification on the VR-T7) contribute to a higher price point.
Built-in Computing and User Interface: The inclusion of advanced components like an i5-1005G7 processor, Windows 11 operating system, and an 11.6" touchscreen (as seen in the VR-T6) influences the overall cost.
Overall Feature Set and Performance: The combination of all these components and additional capabilities, like a manual sample XY platform, define the model's performance tier and, consequently, its price.

When purchasing a gold testing machine, you should focus on:
Detection range of elements：Does it support common precious metal elements such as Au, Ag, Pt, Pd, Rh, Cu, Zn, Ni (and their alloying elements).
Accuracy/Resolution (Detection sensitivity)：It is generally expressed in ppm, or an error of ±0.01%. The lower the resolution, the higher the sensitivity. Preferred SDD detector.
Test speed: The result is generally available within 30 to 60 seconds. The faster the speed, the more suitable it is for high-frequency use.
X-ray tube power: The common range is 4W to 50W. The higher the power, the stronger the penetration ability and speed, and the more comprehensive the test, but the price and energy consumption also increase.
Protection and safety certification: Whether there is X-ray safety shielding, interlocking of protective doors, and passing the radiation license certification, etc.
Brand and After-sales Service: Is there local maintenance, on-site service, training support and warranty period (suggested to be one year).
To extend gold tester life & precision, follow these tips:
Wipe the outer shell with a clean soft cloth or lint-free cloth every day to prevent dust accumulation.
Before each use, check whether there are any foreign objects or contamination in the test window and keep it clean and transparent.
Clean fans and vents regularly to prevent blockage and overheating.
Keep room temperature between 15-30°C and humidity below 70%, avoiding moisture or direct sunlight.
Use a voltage stabilizer or UPS to prevent unstable voltage from damaging components
Avoid prolonged continuous high-load use and turn off the cooling regularly.
For optimal operation and safety, always preheat and calibrate the instrument strictly daily. Ensure the protective door is closed before testing to prevent X-ray leakage. It is recommended to use a regulated power supply or UPS to avoid damage from voltage fluctuations. Keep the working environment dry, clean, and well-ventilated, avoiding high temperature and humidity. Crucially, always follow the operation manual and manufacturer's training, refraining from unauthorized parameter modifications.
Improper operations can pose significant risks. Starting a test with the protective door open can cause X-ray leakage and radiation damage. Forcibly cutting power or frequently turning the machine on and off can damage the X-ray tube, high-voltage module, or hard disk, leading to system crashes. Operating in a humid, hot, or dusty environment may cause overheating, mainboard dampness, or detector malfunction/short-circuit. Unauthorized modification of software parameters or calibration data can distort results, potentially requiring factory recalibration. Touching the detector window with sharp objects or fingers will damage the detector film, incurring extremely high maintenance costs. Lastly, moving the sample or opening the door during a test causes sample position shifts, leading to test failure and X-ray exposure.
If you want to purchase the best XRF analyzer, finding an experienced and technically proficient gold testing machine manufacturer is crucial. Special attention should be paid to the supplier's technical support and emergency issue handling. Below are VRAY's technical support and emergency/contingency issue handling solutions:
