Watch the video below to explore our VRAY's gold tester quality control!
At VRAY, ensuring the highest quality control for every Gold Tester and XRF Analyzer we produce is paramount. We implement a multi-faceted approach, combining specialized expertise, advanced systems, and rigorous processes to guarantee superior precision, accuracy, and reliability.
Professional Quality Inspection Department:VRAY boasts a dedicated and highly professional Quality Inspection Department. This team comprises experienced engineers and technicians who specialize in the intricate workings of XRF technology and precious metal analysis. They are responsible for implementing stringent quality protocols at every stage of production, from initial component inspection to final product verification. This specialized focus ensures that all Gold Testers and XRF Analyzers meet VRAY's demanding internal standards, which often exceed industry benchmarks. Their expertise is crucial in identifying even the slightest deviations, guaranteeing that only flawless devices reach our customers.
Scientific, Precision Testing System:Our Gold Tester & XRF Analyzer Factory is equipped with a scientific and highly precise testing system. This includes state-of-the-art calibration labs featuring certified reference materials (CRMs) traceable to international standards. Every XRF analyzer undergoes multiple layers of automated and manual testing to verify its performance across a wide range of elements and concentrations. We conduct long-term stability tests, environmental simulations, and detailed precision and accuracy validations (e.g., confirming 0.01% accuracy for 9999 gold). This rigorous, data-driven testing ensures that each Gold Tester delivers consistent, reliable results under various operating conditions.
Rigorous and Standardized Assembly Department:The foundation of our quality lies in our rigorous and standardized Assembly Department. Within our smart, dust-free workshops, highly trained technicians follow strict, documented assembly protocols. Each component, from the X-ray tube and SDD detector to the internal wiring and casing, is meticulously installed according to precise specifications. We employ lean manufacturing principles to minimize errors and maximize efficiency. After assembly, an initial battery of functional tests is performed. This meticulous and standardized approach in the assembly phase significantly contributes to the inherent stability, durability, and long-term performance of every Gold Tester and XRF Analyzer we manufacture.
At VRAY, our commitment to superior Gold Tester & XRF Analyzer Quality Control is proven by stringent international certifications for our gold testing equipment:
ISO 9001:2015 Quality Management System: This certifies our comprehensive quality management across design, production, and service for all XRF analyzers, ensuring consistent quality.
CE (Conformité Européenne) Certification: All our Gold Testers bear the CE mark, confirming compliance with EU health, safety, and environmental protection directives for sales within the European Economic Area.
RoHS Compliance: Our XRF equipment adheres to RoHS directives, guaranteeing it's free from hazardous substances like lead and mercury, reflecting our environmental responsibility.
FCC Compliance: For the US market, FCC certification confirms our XRF analyzers meet electromagnetic interference limits, preventing interference with other electronics.
Calibration Certificates (e.g., NIST Traceable): Each Gold Tester comes with a calibration certificate, verifying its accuracy and precision against international standards like NIST, ensuring reliable and traceable measurements.
Radiation Safety Compliance (e.g., IEC 61010-1): Our XRF equipment complies with international safety standards for electrical equipment, ensuring radiation containment and operator safety.
When evaluating the quality of a gold tester, especially an XRF Analyzer, it's crucial to go beyond just initial impressions. Here's how you can rigorously assess its performance and reliability:
Verify Accuracy with Certified Reference Materials (CRMs): The most reliable method is to test the gold tester using Certified Reference Materials (CRMs) of known gold purity (e.g., 10K, 14K, 18K, 22K, 24K). The tester's readings should consistently match the certified values within its stated accuracy specifications (e.g., 0.01% for 9999 gold). Repeat tests on the same CRM to check for precision and repeatability.
Test a Range of Alloys and Elements: A high-quality gold tester should accurately identify and quantify not just gold, but also common alloying elements like silver, copper, nickel, and zinc, as well as potential heavy metal contaminants. Test samples with varying compositions to ensure its analytical capabilities are broad and precise.
Assess Repeatability and Reproducibility: Run multiple tests on the same sample under identical conditions to check for repeatability (how close consecutive measurements are). Then, if possible, have different operators test the same sample to assess reproducibility (consistency between different users). High repeatability and reproducibility are hallmarks of a reliable XRF Analyzer.
Evaluate Stability Over Time: A good gold tester should maintain its calibration and accuracy over extended periods. Check for any drift in readings or a need for frequent re-calibration. Long-term performance is key to its practical utility.
Check for Non-Destructive Nature: Confirm that the gold tester leaves no marks, scratches, or alterations on the tested items, upholding its promise of non-destructive analysis.
Review Software and User Interface: The software should be intuitive, easy to navigate, and provide clear, comprehensive reports. Data management and connectivity options (e.g., Wi-Fi, USB) also contribute to overall quality and user experience.
