No need to bundle samples. Following value can be displayed precisely and quickly with only two procedure:

(1)  Karat value, percentage content, density, weight for gold

(2)  PT value, percentage content, density, weight for platinum

(3)  S value, percentage content, density, weight for silver

(4)  Percentage content, density for other alloy.

(5)  Density, weight for all kinds of solids materials.


Measuring Type:

Precious metals such as Gold, Karat Gold, Platinum, Silver.

Mixed Metal or other Alloy Metal.

Jewelry materials such as Ring, Necklace, Bracelet, Watchband, Belt Fastener, Gold Ingot, Gold Bar, Statue, Coin, etc.

Important Notes:

Please consider the following points before purchasing:

(1)  Products which are inside hollow

       -  If the hollow section is closed, water or other liquids can't get access into the samples, can't be tested

       -  If the hollow section is opened, water or other liquids can get access into, the samples can be tested

(2)   Products set with precious stones can't be tested

(3)   Products of which the density is very close to precious metal can't be tested
