Gold Tester – Purity Density Tester | GKS-300

Upgrade your verification process with the GKS-300, the high-precision standard for professional precious metal analysis. Unlike basic models, the GKS-300 is engineered to detect sophisticated fraud—including under-karated items and "filled" gold (such as gold-plated tungsten)—without damaging the asset.

Utilizing advanced specific gravity technology, this unit allows you to verify stamps and purity in just 20 seconds. It eliminates the need for hazardous acids, needles, or test stones, ensuring your inventory remains in pristine, scratch-free condition. With a high resolution of 0.001g, the GKS-300 offers superior sensitivity, allowing for the accurate measurement of small samples as light as 2g.

Key Features & Capabilities

• Advanced Fraud Detection: Instantly identifies if the gold purity is lower than the marked stamp. Capable of detecting "sandwich" metals (gold/platinum covering a non-precious core).
• Comprehensive Metal Support: Features dedicated modes for Gold, White Gold, Platinum, and Silver.
• Scrap Gold Analysis: Measure a batch of scrap gold at once to determine the average purity efficiently.
• Dual Functionality: When not testing purity, the unit functions as a high-precision gram scale and Densimeter.
• User-Friendly Interface: Features selectable Specific Gravity (SG) display and automatic calculative tolerance to reduce operator error.

Why Choose the GKS-300?

• ✔ Non-Destructive: Leaves zero scratches, stains, or chemical residue on merchandise.
