VR-X5 ($10,000-$11,000): A mid-range Silver Gold Tester. Boasts a customized USA-made Si-Pin detector for enhanced 0.05% accuracy for 9999 gold, with a faster 40-second test time. It offers versatility by testing solid, liquid, and powder samples, covering elements from K(19) to U(92).
VR-T7 ($20,000-$22,000): Our premium Silver Gold Tester solution. Equipped with a high-sensitivity SDD detector, it delivers ultimate 0.01% accuracy for 9999 gold in just 30 seconds. This model handles solid, liquid, and powder samples, featuring a fine ϕ1.5mm collimator, a manual XY platform for precise sample positioning, and a high-resolution 5MP camera (40x-160x magnification) for detailed analysis.
All VRAY Silver Gold Testers utilize a 50W micro-focused X-ray tube and integrate robust thermal management. Customization options primarily involve selecting the model that precisely aligns with your specific analytical requirements, desired accuracy, sample versatility, and budget.
A Silver Gold Tester (desktop XRF analyzer) has core components: an X-ray tube (excites samples), a detector (e.g., Si-Pin/SDD, captures secondary X-rays), a collimator, and a sample chamber. An integrated computer with software processes data, enclosed by safety shielding.
Principle of silver gold tester is X-ray Fluorescence (XRF): The X-ray tube irradiates the sample, making atoms emit unique secondary X-rays. The detector measures their energy (identifying elements) and intensity (determining concentration). The computer then analyzes this data to provide precise elemental composition and purity results for gold, silver, and alloys.
1.Power On: Turn on the machine and launch the software.
2.Preheat: Allow the instrument to preheat for 10 minutes.
3.Calibrate: Place the calibration sample in the detection area and perform instrument calibration.
4.Load Sample: After calibration, remove the calibration sample and place your test sample in the detection area.
5.Start Test: Close the machine cover and press the "Start" button to begin the test.
6.Await Results: A preliminary analysis result is typically displayed within 3 seconds. The complete analysis result will be available within 30 seconds.
7.Report Handling: When the test is complete, select the "Print" icon. Choose to print either an A4 report or use the Bluetooth thermal printer.
Note: You can also choose to save the report directly without printing at this time.

A Silver Gold Tester provides rapid, non-destructive elemental analysis to precisely determine the authenticity, karat level, and purity of gold, silver, and other precious metals. It plays a crucial role in verifying raw materials, ensuring production quality, optimizing alloy ratios, and detecting counterfeit or plated items. This technology generates professional, printable/exportable reports, building trust and supporting standardized, high-precision analysis for a wide range of elements.
Silver Gold Testers are essential tools across various professional environments:
Jewelry Stores / Gold Retail Chains: Utilized for gold jewelry sales, K-gold identification, and customer recycling processes.
Gold Recycling / Pawnshops / Secondhand Precious Metals: Employed for on-site testing of gold/silver jewelry, coins, and scrap materials.
Jewelry Manufacturers / Precious Metal Factories: Critical for raw material inspection, quality control throughout production, and efficient batch testing.
Third-Party Labs / Certification Authorities: Used for generating official analysis reports and providing professional inspection services.
A Silver Gold Tester is vital for various professionals. When purchasing, evaluating core specifications is crucial to ensure optimal performance and suitability for your specific needs.
| Who Needs It | Key Purchase Considerations |
|---|---|
| Jewelry Retailers/Store Owners | Elements: Au, Ag, Pt, Pd, Rh, Cu, Zn, Ni + alloys. |
| Gold Recyclers / Pawnshops | Accuracy: ppm / ±0.01% (SDD preferred). |
| Jewelry Mfrs / Metal Factories | Test Speed: 30-60s (faster for high-frequency use). |
| Coin Collectors / Antique Dealers | X-ray Tube Power: 4W-50W (higher = better penetration/speed vs. cost). |
| Testing Labs / Cert. Bodies | Safety: X-ray shielding, interlocks, radiation license. |
| Service: Local maintenance, training, 1-yr warranty. |
To ensure the longevity and optimal performance of your Silver Gold Tester, regular maintenance is crucial. Daily, wipe the outer shell with a clean, soft, lint-free cloth to prevent dust accumulation. Before each use, inspect the test window for any foreign objects or contamination, keeping it clean and transparent. Regularly clean fans and vents to avoid blockage and overheating. Maintain the room temperature between 15-30°C and humidity below 70% to prevent moisture or direct sunlight damage. Always use a voltage stabilizer or UPS to protect components from unstable voltage. Finally, avoid prolonged continuous high-load operation and ensure regular cooling downtime.
For comprehensive support, our services cover Installation Instructions, facilitating proper setup from the start. at VRAY, We provide regular Software Updates to ensure your system is current and efficient. Detailed Technical Training is available to help users master the equipment. All hardware comes with a Hardware Warranty, and immediate assistance is provided through Remote Guidance for quick problem resolution.
For safe operation of your Silver Gold Tester, strict adherence to guidelines is paramount. Always preheat and calibrate the instrument daily upon startup. Crucially, ensure the protective door is tightly closed before starting any test to prevent X-ray leakage and potential radiation damage to the operator. Using a regulated power supply or UPS is highly recommended to protect against voltage fluctuations, which can damage the X-ray tube, high-voltage module, or hard disk, leading to system crashes. Maintain a dry, clean, and well-ventilated working environment; humid, hot, or dusty conditions can cause overheating, mainboard dampness, or detector malfunctions. Never forcibly cut power or frequently turn the machine on/off. Strictly follow the operation manual and manufacturer's training; unauthorized modification of software parameters or calibration data can distort results and incur high recalibration costs. Furthermore, never touch the detector window with sharp objects or fingers, as this will damage the detector film and result in extremely high maintenance costs. Lastly, avoid moving the sample or opening the door during a test, as this can cause sample shifts, test failure, and potential X-ray exposure.
