FAQS about handheld XRF analyzer
1. What is a Handheld XRF Analyzer, and what elements/materials can VRAY's models detect?
A Handheld XRF Analyzer is a portable, non-destructive device quantifying elemental composition using X-ray Fluorescence (XRF) technology. VRAY's models, like the VR-H5, can detect 74 kinds of precious metal elements, including Au, Ag, Cu, Pd, and Rh, within a K-U range. They are ideal for testing karat gold, platinum jewelry, coins, and alloys, suitable for solid, liquid, and powder samples.
2. How accurate and reliable are the results from VRAY's Handheld XRF Analyzer?
Our Handheld XRF Analyzers, featuring a Customized Si-Pin detector from USA and advanced calibration algorithms, ensure high accuracy and repeatable results. The VR-H5, for instance, boasts 0.05% accuracy for 9999 gold, with typical accuracy within ±0.01% to ±0.1% depending on configuration. Regular calibration with provided standards ensures long-term stability and reliability for daily use.
3. How quickly does VRAY's Handheld XRF Analyzer provide test results?
Answer: VRAY's Handheld XRF Analyzers are designed for rapid analysis. They typically provide preliminary analysis data in about 3 seconds, with complete and accurate elemental composition results displayed within a quick 20 to 30 seconds. This fast scanning allows for immediate decision-making, even for bulk compositions.
4. Is VRAY's Handheld XRF Analyzer easy to operate, and can it handle various sample types?
Absolutely. Our analyzers feature a user-friendly interface with graphical guidance and one-button operation, making them very easy to use even for non-technical staff, usually requiring only 30 minutes of basic training. While flat contact yields best results, the device can effectively handle uneven surfaces and test various forms like solids, liquids, and powders.
5. Can VRAY's Handheld XRF Analyzer accurately identify gold purity (Karat), plated gold, or fake gold?
Yes. Our analyzers excel in distinguishing between pure gold, various gold alloys (e.g., 18K, 22K), and plated materials with high sensitivity. The system automatically calculates and displays K-values (e.g., "Au 75% = 18K") and will alert you to abnormal structures, helping identify fake or plated items. The multi-functional sample holder also assists in testing small items like rings or earrings.
6. Is VRAY's Handheld XRF Analyzer safe to use, with no radiation risk for the operator?
Yes, our devices are designed with multiple safety features to ensure operator safety. They include robust X-ray shielding, an automatic X-ray shutdown system when not in use, and meet international safety standards. When used as instructed, radiation is fully contained, posing no risk. For frequent testing of small samples, using a bench-top stand is recommended to minimize scattered radiation.
7. What are the data management capabilities, such as saving, exporting, and printing reports, on VRAY's Handheld XRF Analyzers?
VRAY's Handheld XRF Analyzers offer comprehensive data management. All test results are automatically saved locally (e.g., 32GB memory) and can be easily exported via USB or Bluetooth. Reports can be generated in PDF or Excel formats, printable via built-in or external printers, and customizable with your company logo, customer name, and sample details.
8. How long does the battery last on VRAY's Handheld XRF Analyzer, and are there any overheating issues?
Our Handheld XRF Analyzers feature an intelligent battery system providing long operational life, typically 5 to 8 hours of continuous use per charge. They are equipped with a dedicated T-shaped radiator and an intelligent cooling system to prevent overheating, ensuring stable performance even during extended operation across a wide temperature range (-20℃ to 50℃).
What did our happy clients say?
Recently acquired the VRAY VR-H5 Handheld XRF Analyzer. Its portability at just 1.6Kg is incredible for our field work. The 0.05% accuracy for gold is very reliable, and the 30-second test time is efficient. The 8-hour battery life is a huge plus. Highly recommend!
Just purchased the VRAY VR-H5 Handheld XRF Analyzer. The customized USA Si-Pin detector delivers excellent precision. I'm particularly impressed with the wide operating temperature range of -20℃ to 50℃. It's rugged and reliable. Definitely recommend this handheld unit!
Our pawn shop recently invested in the VRAY VR-H5 Handheld XRF Analyzer. The quick 30-second testing helps streamline transactions. The ability to adjust the excitation source up to 50KV/200μA provides versatility for different samples. A fantastic tool – highly recommended!
I'm very satisfied with the VRAY VR-H5 Handheld XRF Analyzer I recently bought. The 4.3" industrial resistive touch screen is easy to use, and the 32GB memory is ample for storing data. The Bluetooth data transmission is also very convenient. I highly recommend this handheld analyzer!
