A Gold Quality Testing Machine is an X-ray Fluorescence (XRF) instrument designed for non-destructive analysis of precious metals.
X-ray Tube: Typically a 50W micro-focused X-ray tube (tungsten target, often with a beryllium window for enhanced performance). This generates the primary X-ray beam.
Detector: High-precision Si-Pin (Silicon PIN Diode) or SDD (Silicon Drift Detector) are standard. SDD offers superior resolution and speed, leading to higher accuracy.
Collimator: Controls the X-ray beam size (e.g., ϕ1.5mm, ϕ2.5mm).
Inbuilt Computer: Modern machines often feature integrated Intel i5 (or newer) processors with Windows 11 for powerful data processing.
Screen: An 11.6" touchscreen provides an intuitive user interface.
Power/Cooling: Rated power around 100W, with a dedicated T-shaped radiator ensuring stable operation without overheating or cooling waits.
Accuracy: Ranges from 0.01% to 0.05% for 9999 gold.
Test Time: Fast analysis, typically 30-40 seconds.
Test Range: Capable of testing solid, liquid, and powder samples.
VRAY's Gold Quality Testing Machines are indispensable tools that solve a myriad of critical issues for anyone dealing with precious metals. Primarily, they provide rapid, non-destructive, and highly accurate analysis, identifying the exact elemental composition and karatage of gold, silver, platinum, and other valuable metals.
These advanced gold testing instruments are vital for jewelers, pawn shop owners, gold recyclers, refineries, banks, and even individual collectors. In retail environments, they immediately prevent fraud by detecting counterfeit items or under-karat gold, safeguarding businesses from significant financial losses. For buyers and sellers, they ensure fair and transparent valuations, eliminating guesswork and building trust in every transaction. In industrial settings like refineries and manufacturing, they are crucial for rigorous quality control, verifying material consistency and purity throughout production processes. By offering fast analysis—often in mere seconds— these machines drastically improve efficiency in high-volume operations, streamlining appraisals and material sorting. Furthermore, their non-destructive nature means valuable items remain intact, preserving their market value. Ultimately, VRAY's Gold Quality Testing Machines empower professionals with the precise, reliable data needed to make informed decisions, mitigate risks, and enhance operational integrity across the entire precious metals supply chain.
VRAY's Gold Quality Testing Machines are designed for precise, non-destructive analysis, but proper operation and safety are key. Here's how to use your machine effectively, along with vital safety considerations:
Power On & Warm-Up: Connect your machine to a stable power supply (ideally with a UPS). Turn it on and allow any necessary self-checks or warm-up cycles to complete, usually displayed on the screen.
Sample Preparation: Ensure your gold item is clean and dry. Remove any dirt, oil, or residues that could interfere with the X-ray beam. For best results, place the sample on a flat surface or use the provided sample holder for irregular shapes.
Position the Sample: Carefully place the gold item inside the machine's test chamber, ensuring it's stable and directly beneath the X-ray window. Close the chamber door securely.
Select Test Mode: Use the intuitive touchscreen interface (e.g., 11.6" on VR-T6/VR-S7) to select the appropriate test mode for gold analysis (e.g., "Karat Test," "Precious Metals Analysis").
Initiate Scan: Press the "Start" or "Analyze" button. The machine will begin emitting X-rays for a short duration (typically 30-40 seconds). The chamber door will lock during this process, and an indicator light will confirm X-ray activity.
Review Results: Once the scan is complete, the detailed analysis will appear on the screen, showing precise gold purity (e.g., 18K, 24K) and the percentages of other detected elements like silver, copper, or platinum.
Data Management: Save the results to the machine's internal memory (e.g., via the inbuilt i5 computer) or export them via USB for record-keeping, printing, or further analysis.
VRAY Gold Quality Testing Machines use X-ray technology, making radiation safety paramount. Always follow these critical precautions:
Never open the test chamber or place any body part inside during operation. All VRAY machines are equipped with safety interlocks that prevent X-ray emission if the chamber is open. Do not attempt to bypass these safety features.
Keep all body parts, especially fingers, completely clear of the X-ray emission window when the machine is active.
Operate the machine only as intended and strictly according to the user manual. Only trained and authorized personnel should use the device.
Do not extend test times unnecessarily. Limit X-ray exposure to the minimum required for analysis.
Do not attempt to open the machine or perform repairs/maintenance yourself. Only qualified, certified technicians (ideally from VRAY or an authorized service center) should handle internal components or repairs. Unauthorized tampering can lead to radiation leakage and void your warranty.
Ensure proper environmental conditions. Operate and store the machine within the specified temperature range (10℃–35℃) and in a clean, dry, dust-free environment. Use a stable power supply, preferably with a UPS, to protect the delicate X-ray tube and electronics from power fluctuations.
Benefit from VRAY's dedicated T-shaped radiator. This advanced cooling system ensures the machine dissipates heat efficiently, allowing for continuous operation without needing to wait for cooling, which also contributes to component longevity.
By adhering to these operational steps and safety guidelines, you'll ensure both accurate testing and a safe working environment when using your VRAY Gold Quality Testing Machine.
