-
Choosing the Right Instrument: By Use Case
| Use Case | Recommended Instruments |
| High accuracy for bulk or lab use | XRF analyzers (Vanta GX, Bruker, VRAY) |
| Portable on-the-go testing | Handheld XRFs, AuRACLE, Sigma Metalytics |
| Fast retail checks | Specific gravity kits (Qualitest) |
| Budget-conscious, small-scale use | Analog testers like KEE, AuRACLE |
| Traditional backup method | Touchstone + acid tests (with caution) |
Key Considerations When Choosing a Testing Instrument
Selecting the right instrument depends on several factors specific to your business:
- Business Type & Volume: A high-volume refinery needs a high-capacity density meter or XRF, while a pawnshop might prioritize a fast electronic tester.
- Required Accuracy: For buying and selling, precision is critical. Density meters and XRF analyzers offer the highest accuracy.
- Testing Needs: Determine if you need to test only gold or also silver, platinum, and other PGMs. Not all devices can handle all metals.
- Sample Size and Type: Do you test tiny jewelry pieces or large bars? This will dictate the capacity you need.
- Budget: Balance upfront cost with long-term value, factoring in maintenance, consumables (like acid or probes), and potential business loss from inaccurate readings
-
What to Consider When Buying

Gold density testing measures the mass of an item in air and water to determine its specific gravity—a key indicator of purity. Devices like the Qualitest GK and GKS Series offer fast, non-destructive testing, making them ideal for retail environments and gold-buying businesses.
What Is Karat Testing?
Karat testing is used to measure how pure a piece of gold is, with the purity level represented in karats—where 24K signifies 100% pure gold. Modern electronic testers, such as the AuRACLE AGT3 or KEE Gold Tester, use conductivity or resistance measurements to deliver accurate karat readings without chemicals or damage.
Why Choose These Methods?
- Non-destructive: No scratching or acid required
- Fast and easy: Results in seconds
- Cost-effective: Ideal for everyday use
- Accurate: Trusted by professionals globally
Whether you’re testing scrap, coins, or jewelry, density and karat testers provide a simple and safe way to verify gold purity and build trust with your customers.
