Gold Purity Density Tester

GKS-300 Electronic Gold & Precious Metal Purity Tester

The GKS-300 is a professional electronic precious metal tester designed for accurate, non-destructive analysis of gold, white gold and platinum.

Using advanced specific gravity measurement technology, the GKS-300 calculates metal density to help determine purity and verify whether precious metal items correspond with their marked karat or fineness.

Unlike traditional acid testing, the GKS-300 does not require scratching, cutting or applying chemicals to the item being tested. This makes it particularly useful for jewellery businesses and precious metal dealers looking to assess valuable items without causing damage.

Key Features

• Non-Destructive Testing: Assess precious metal purity without acids, scratches or chemical residue.
• High-Precision Measurement: 0.001g weighing resolution and 0.001g/cm³ density resolution.
• Gold Karat Testing: Displays gold purity from 9K to 24K, including intermediate karat values.
• Multiple Metal Applications: Suitable for gold, white gold and platinum testing.
• Small Sample Capability: Tests samples weighing as little as 2g.
• Purity Verification: Helps identify items with purity lower than their marked karat or fineness.
• Digital Readout: Displays calculated purity, weight and density measurements.
• Additional Functionality: Can also be used as a precision electronic balance and densimeter.
