When Handheld Jewelry Testing Machine Is the First Choice

A Handheld Jewelry Testing Machine like the VRAY VR-H5 is the first choice in specific scenarios where mobility and on-site analysis are paramount:

• Mobile Gold & Silver Buyers: For individuals or businesses that travel to buy precious metals from private sellers, estate sales, or remote locations, needing immediate, accurate appraisals.

• Pawnshops: To quickly and reliably assess the value of incoming jewelry and precious metals directly at the counter, even if they have limited counter space for a large desktop unit.

• Jewelry Fairs, Trade Shows & Auctions: For vendors and buyers who need to verify purity and authenticity on the spot without relying on off-site testing or bringing bulky equipment.

• Field Appraisers & Valuers: Professionals who visit clients' homes or businesses to appraise high-value jewelry collections.

• Quality Control in Remote Manufacturing/Recycling: For initial checks of precious metal scrap or raw materials at collection points or smaller processing sites before transport.

• Law Enforcement & Customs: For rapid screening of precious metals to identify contraband or fraudulent items at border crossings or during investigations.

• Any situation where immediate, non-destructive analysis is required, and bringing the sample to a fixed lab is impractical or impossible.

Usage Guide and Important Reminders

Usage Guide:

1. Power On: Ensure the battery is fully charged or connected to power. Long-press the power button to start the device.

2. Select Test Mode: On the 4.3" industrial resistive touch screen, select the appropriate test mode for your needs (e.g., gold, silver, platinum, or other alloys).

3. Sample Preparation & Placement:

1. Clean Sample Surface: Ensure the surface of the jewelry to be tested is clean and free of dust, dirt, or oil, as this may affect the accuracy of the test results.

2. Ensure Tight Contact: Place the instrument's test window (usually on the bottom) directly and firmly against a flat surface of the item being tested. For irregularly shaped items, try to find a flat contact point.

4. Initiate Test: Press the test button (usually a trigger or a virtual button on the screen). The instrument will begin emitting X-rays and performing the analysis.

5. View Results: After approximately 30 seconds, the test results will immediately display on the screen, including elemental percentages and karat values.

6. Save & Transfer Data: You can save results to the 32GB memory and transfer them to a computer via USB or Bluetooth for report generation or archiving.

7. Power Off & Charging: Properly shut down the instrument after completing your tests. When the battery is low, use the original charger to recharge the intelligent battery.

Important Reminders:

1. Safety Operation:

1. Never Test on People or Living Organisms: X-rays are harmful to humans. Always ensure the test window is aimed at the item to be tested and away from any person.

2. Comply with Local Radiation Safety Regulations: Understand and adhere to all radiation safety regulations regarding XRF equipment use in your region.

3. Keep Out of Reach of Children: Store the device where children cannot access it.

2. Sample Limitations: Although capable of testing solids, liquids, and powders, the VR-H5 is handheld and primarily used for solids. Testing liquids and powders usually requires additional safety measures (such as in a sealed container) and professional guidance.

3. Surface Cleanliness & Influence: Surface plating, dirt, or thick oxidation layers can affect results. If plating is suspected, additional scratch tests (in a non-critical area) or other methods may be needed for confirmation.

4. Optimal Test Position: For non-uniform alloys, it's recommended to perform multiple tests at different points and average the results for more accurate overall composition.

5. Battery Management: The intelligent battery can work for approximately 8 hours. It's advisable to ensure the battery is fully charged before use and carry a spare battery or charger for extended field operations.

6. Environmental Temperature: Although it can operate between -20℃ to 50℃, extreme temperatures may slightly affect battery performance and instrument stability. Try to use it within an optimal temperature range.

7. Regular Maintenance & Calibration: Follow VRAY's maintenance guidelines for daily cleaning and perform regular calibration checks to ensure the 0.03% accuracy is maintained.
