Gold Density Meter is a precision instrument used to measure the density or purity of gold and other precious metals. It operates based on the principle of buoyancy or displacement, following Archimedes’ law, ensuring accurate and non-destructive testing.

This device is essential in jewelry making, pawnshops, and gold trading to verify authenticity and karat value. By comparing the sample’s weight in air and water, it calculates density, distinguishing pure gold from alloys or counterfeit materials.

Modern digital density meters offer fast, user-friendly results with high accuracy, often featuring touchscreens, automatic calculations, and data storage. Portable models enable on-site testing, while advanced versions support multiple metals like silver and platinum.

Key advantages include speed, reliability, and minimal sample damage. Regular calibration ensures consistent performance. The Gold Density Meter is a must-have tool for quality control in the precious metals industry, ensuring trust and compliance with international standards.
