In the gold and silver retail market, trust is the ultimate currency. For decades, jewelers and traders relied on traditional touchstones and acid tests to verify the purity of precious metals. While somewhat effective, these methods are often destructive, require hazardous chemicals, and can be easily manipulated.

Enter NPXSoft's Metal Purity Lab a digital breakthrough that is fundamentally changing how jewelry shops operate.

The Science of Purity: Archimedes Principle

Our software utilizes the Archimedes principle, a law of physics stating that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.

By accurately measuring the weight of a metal in the air and then in water, Metal Purity Lab calculates the density of the object. From there, it cross-references the density with our database of 18+ International Standards (such as PKIN, ISO, EU, and US standards) to determine the exact Karat and fineness.

Why This is a Game-Changer for Jewelers

• 99.9% Accuracy: Digital precision eliminates human error. You know exactly what you are buying or selling.
• Non-Destructive: Unlike acid tests that scratch or damage the jewelry, digital density testing leaves the item completely intact.
• Instant Reports: Generate professional PDF purity reports with your shop's branding to show customers proof of authenticity.
• Multi-Unit Support: Instantly convert results into Grams, Tola, Masha, and Ratti to suit local market preferences.

Combining Testing with Billing

What makes this suite truly powerful is its integration with JBS Jewelry Billing System on Android. Once the metal purity is verified on the Windows PC, the data can be used to generate precise, live-rate invoices instantly.

Shops that use this dual-app approach report massive reductions in errors, faster checkout times, and higher customer trust. By combining scientific precision with modern POS software, NPXSoft is defining the future of jewelry retail.
