When you choose VRAY, you're investing in a Precious Metal Tester that delivers superior analytical capabilities, backed by our expertise as a dedicated Precious Metal Tester manufacturer and your trusted Precious Metal Tester supplier.
Precious Metal Testers, primarily utilizing X-ray Fluorescence (XRF) technology, are indispensable tools across numerous sectors due to their ability to provide accurate and non-destructive elemental analysis of precious metals.
Jewelry Retail & Pawn Shops: Crucial for immediate, accurate karat identification (e.g., 10K, 14K, 18K, 24K) and verifying the composition of gold, silver, platinum, and palladium items. This ensures fair pricing for buyers and sellers, and authenticates pieces against fakes or plated items.
Gold Refining & Recycling: Essential for quickly assessing the purity of incoming scrap, doré bars, and other gold-bearing materials, optimizing the refining process, and guaranteeing the quality of the refined product.
Bullion & Coin Dealers: Used to verify the authenticity and precise purity of gold and silver bars, coins, and investment-grade precious metal products, protecting against counterfeits.
Manufacturing Quality Control: Manufacturers of gold components, plated items, or dental alloys use these testers to verify alloy composition, coating thickness, and identify contaminants, ensuring product quality and compliance.
Customs & Border Security: Aid authorities in rapidly screening precious metal shipments, detecting undeclared valuables, and combating smuggling activities.
Using a Precious Metal Tester (specifically an XRF model) is a straightforward process, designed for efficiency and safety.
Preparation: Power on the tester and allow it to complete its self-calibration. Ensure the surface of the precious metal item is clean and free of dirt, oils, or heavy oxidation, which could affect accuracy.
Safety First: Always follow the manufacturer's safety instructions. For handheld units, ensure the tester's nose is pressed firmly against the sample. Desktop units have safety interlocks to prevent X-ray exposure when the chamber is open.
Sample Placement: Place the precious metal item directly against the tester's measurement window. For rings or oddly shaped items, ensure the part being analyzed is flat against the window. For desktop models, place the item in the sample chamber.
Select Test Mode: Choose the appropriate testing mode (e.g., "Gold," "Precious Metals," "Jewelry") from the tester's software interface.
Initiate Analysis: Press the "start" button or pull the trigger. The test usually takes only a few seconds. Keep the item steady during analysis.
Review Results: The tester will display the karatage, elemental composition (e.g., % gold, silver, copper), and often a pass/fail indication directly on its screen.
