Precious Metal Purity-Karat Density Tester
The TTDS-PM-Karat Precious Metal Purity Tester is a professional-grade solution for the non-destructive analysis of gold, silver, and platinum. Built in strict accordance with ASTM D297 standards, this industrial density tester utilizes the Archimedean principle to determine the exact karat value and purity of precious metal alloys. By measuring the specific gravity of the entire sample rather than just the surface, the device provides a comprehensive assessment that is essential for gold refining, recycling operations, and laboratory quality control.
Engineered for high-stakes environments, this digital karat tester is a critical asset for the jewelry industry, the banking sector, and pawn shops. It enables professionals to verify the authenticity of precious metal assets for financial transactions and ensure transparent, fair pricing during trade. With three specialized models—TTDSPrecMetIII, V, and XII—the series supports a wide range of sample weights from 5g to 1200g, making it a versatile tool for everything from intricate jewelry pieces to substantial bullion bars.
The TTDS series delivers exceptional measurement accuracy, featuring a density precision of 0.001g/cm³ and a display range reaching 24K and 100% purity. Its streamlined operation allows for rapid, standardized testing without damaging the material, ensuring both operational efficiency and sample integrity. For organizations requiring a reliable, compliant, and easy-to-use analyzer, the TTDS-PM-Karat stands as the industry standard for precise precious metal verification and purity assessment.
