This dual functionality is delivered with unparalleled speed and accuracy.
Our VR-S7 High Precision Desktop Gold Tester is a flagship offering. Equipped with a High Sensitivity SDD detector, it achieves an exceptional 0.01% accuracy for 9999 gold, setting a new industry standard. Its powerful 50W micro-focused beryllium window X-ray tube ensures robust analysis in just 20 seconds for solid, liquid, or powder samples. The manual sample X/Y platform with a seeing scope 30x/50x and high-resolution 5-megapixel CMOS camera provides precise sample positioning and clear observation, crucial for detailed diamond and gold inspection. The integrated T-shaped radiator guarantees continuous, stable operation without cooling waits, ensuring consistent performance even under high usage.
For professionals requiring mobility without compromising on precision, the VR-M5 Mini-size Portable Gold Tester offers an ideal solution. Featuring a Customized Si-Pin detector from USA, it delivers 0.05% accuracy for 9999 gold in 20 seconds for all sample types. Its 5.7" retractable color touch screen and built-in 5-million high-definition camera provide excellent usability and visual inspection, even on the go. The VR-M5 also benefits from the efficient T-shaped radiator for reliable, continuous field operation, supporting a wide temperature range of -20℃ to 50℃.
VRAY provides cutting-edge Diamond Gold Tester solutions that are synonymous with accuracy, speed, and reliability. As a dedicated manufacturer and supplier, we ensure our instruments, including the VR-S7 and VR-M5, offer the best technical solutions for comprehensive precious metal and diamond screening, enhancing efficiency and trust in every transaction.
A Diamond Gold Tester combines X-ray Fluorescence (XRF) for metals with specialized diamond screening. For precious metals, XRF directs a precise X-ray beam onto the sample. This excites atoms, causing them to emit unique secondary X-rays. High-precision detectors (like VRAY's Si-Pin or SDD) capture these signals. Integrated software rapidly analyzes the spectrum to determine exact elemental composition and purity (e.g., gold karatage, percentages of other elements), displaying results in mere 20-30 seconds. This method is entirely non-destructive, preserving the item's integrity. For diamond testing, these devices commonly employ principles like thermal conductivity to distinguish diamonds from simulants (e.g., CZ, moissanite). More advanced testers might utilize UV or electrical conductivity to screen for natural versus lab-grown diamonds (HPHT/CVD). High-resolution cameras and seeing scopes further aid visual inspection and inclusion analysis. This comprehensive dual technology ensures rapid, accurate, and non-invasive authentication for both metal and stone components in jewelry.
Using a Diamond Gold Tester involves precise steps. First, power on the machine and its software, allowing for warm-up (e.g., 10 minutes for XRF). Calibrate daily with certified reference samples for accuracy. For metal analysis, ensure your item is clean and dry, then carefully place it on the platform within the test chamber. For diamond testing, position the stone on its specific point. Securely close the chamber door; safety interlocks prevent X-ray emission if open. Select the appropriate test mode (e.g., "Gold Analysis," "Diamond Screen") on the touchscreen. Initiate the test; results typically appear within 20-30 seconds, showing metal purity and diamond verification. Important precautions: Never open the chamber or touch the X-ray emission window during operation due to X-ray presence. Avoid forced power cuts, frequent on/off cycles, or humid/hot/dusty environments, which can damage internal components. Regularly clean the exterior and test window, and use a voltage stabilizer for optimal longevity and safe operation.
Daily Calibration: Strictly preheat and calibrate the instrument according to requirements every day upon the first power-on.
Safety Door Closure: Always ensure the protective door is tightly closed before starting a test to prevent X-ray leakage and radiation exposure.
Stable Power Supply: It is recommended to use a regulated power supply or UPS to avoid damage to the X-ray tube and mainboard caused by voltage fluctuations. Do not forcibly cut off power or frequently turn the machine on/off, as this can severely damage components.
Environmental Control: Keep the equipment's working environment dry, clean, and well-ventilated, avoiding high temperatures, high humidity, and dust (which can lead to overheating, mainboard dampness, or detector malfunction/short-circuit).
Follow Guidelines: Strictly follow the operation manual or manufacturer's training guidelines. Do not privately modify parameter settings or calibration data, as this can distort data and may require factory recalibration.
Detector Protection: Never touch the detector window (e.g., SDD protection film) with sharp objects or fingers, as this will cause damage and incur extremely high maintenance costs.
Stability During Test: During the test, do not move the sample or open the protective door, as this will cause test failure and potential X-ray exposure.
Daily Cleaning: Wipe the outer shell daily with a clean, soft cloth to prevent dust accumulation; check the test window for foreign objects before each use.
Heat Dissipation Maintenance: Regularly clean fans and vents to prevent blockage; avoid prolonged continuous high-load use (VRAY's T-shaped radiator minimizes wait times, but care is still advised).
Element Detection Range: Confirm if it supports analysis of all common precious metals (e.g., Au, Ag, Pt, Pd, Rh, Cu, Zn, Ni) and their alloying elements, and if it meets your specific diamond identification needs.
Accuracy & Resolution: Pay attention to detection accuracy (e.g., ±0.01% or ±0.05% error) and resolution. Lower error means higher sensitivity. SDD detectors (like in VR-S7) are generally preferred for the highest precision.
Test Speed: Evaluate the test cycle time (typically 20 to 60 seconds). For high-frequency use cases like busy jewelry stores or pawnshops, faster test speeds significantly improve efficiency.
X-ray Tube Power: X-ray tube power (common range 4W to 50W) directly affects penetration capability and test speed. VRAY's 50W X-ray tubes offer stronger penetration and more comprehensive testing, but consider the balance with price and energy consumption.
Protection & Safety Certification: Ensure the equipment has X-ray safety shielding, protective door interlocking, and has passed relevant radiation license certifications to guarantee operator safety.
Brand & After-sales Service: Consider the manufacturer's brand reputation, availability of local maintenance, on-site service, training support, and warranty period (a one-year warranty is recommended) to ensure long-term stable operation and technical support.
