Gold Purity tester

Gold Purity, Karat and density tester

A measurement device  to determine purity, density and karat of gold.  Also we known as 99.99% is highest grade gold, which is expressed 24K gold.

100% is 24K / Density is 19.32g/cm³
Most gold is the alloy of silver and copper except 24k (pure gold). For example, 18k include 18/24 (75%)
gold and 6/24 (25%) copper & silver, or silver & copper. Therefore 18K gold products have different
density according to their different ratios.

Principle – Correspond to the buoyancy method of Archimedean principle

gold purity

Gold Karat: copper & silver alloy Shows CS: 23.9K
Means: And this gold has 23.9K and the leave 0.1K is for silver and copper

Gold Karat: silver alloy Shows S: 23.9K
Means: And this gold has 23.9K and the leave 0.1K is for silver.

Gold Karat: copper alloy Shows C: 23.8K
Means: And this gold has 23.8K and the leave 0.2K is for copper.

Have you notice the result: C is higher / S is lower / CS is in the middle.
Hence, customer will take CS result for reference
