• 【2-Step Fast & Precise Testing】Can quickly and accurately determine the purity of precious metals % and gold K number: only two weighing steps.No trace or contamination will be left after the measurement, and there is no need to use sulfuric acid solution or test standard samples.Protect your valuables while getting reliable data.
• 【Non-Destructive Testing to Preserve Value】No cutting, scratching, or altering samples! This tester uses density analysis to assess purity without damaging jewelry, bullion, or collectibles—critical for high-value pieces. Note: It can’t test hollow samples with gems, but it keeps your items’ integrity and worth intact, ideal for jewelers and collectors.
• 【High-Precision Sensor & Multi-Metal Compatibility】Boasts 0.001g weighing accuracy via advanced HBM sensors (low temp drift) and up to 1200g capacity. Tests gold, silver, platinum, and palladium; doubles as a general balance. Supports water/alcohol media with real-time temp calibration. Large tank design reduces buoyancy errors for ultra-stable results.
• 【Portable Rechargeable Design for On-the-Go Use】Built-in rechargeable battery —perfect for trade shows, flea markets, or pawnshops. Compact and lightweight for easy transport; no power outage worries. Clear digital LCD instantly shows weight, density, purity, and karat for quick result interpretation.
• 【Powerful initial screening tools】Designed for jewelers, dealers, and refiners. Features RS-232 output (compatible with optional XF-68 printers) for data documentation. Verifies metal authenticity and matches marked purity fast, streamlining valuation. Versatile for solid precious metals, it’s an essential tool for efficient testing.
