Product Description
Precious Metal Purity, Gold Karat Tester
Suitable for:
Jewelry industry, Bank, Pawn industry,Gold and Precious Metal research lab.
Principle:
According to the buoyancy method of Archimedean principle, can show gold karat, density and purity% rapidly and accurately.
Technical data:
Most gold is the alloy of silver and copper excepting 24K (pure gold). For example, 18K gold includes 18/24 (75%) gold and 6/24 (25%) copper, or silver & copper or silver. Therefore 18K gold products have different densities according to their different ratios. MZ-K1200 can test the karat and density of gold, but can not distinguish the content of alloy. Thus gold karat should be divided into three typical alloy samples: gold-copper alloy, gold-silver-copper alloy, gold-silver alloy. Generally speaking, gold-copper alloy looks reddish, gold-silver alloy looks bluish and gold-silver-copper alloy looks yellowish.
MZ-K1200 can show the gold karat and density directly by testing the gold-silver-copper alloy.
And according to the market demand, by adopting the special design of software, the machine will show "HI" when the gold karat is higher than 24K, and show "LO" when gold karat is lower than 9K.
1. Can show directly the karat, density, purity of Gold, purity% and density of platinum, density of other metals.
2. No stains and scratches left on sample after testing.
3. Only 10 seconds, it can measure karat and density of gold, or purity% and density of platinum (Pt).
4. The operation is simple, only two weighing steps, the purity and density of precious metals and gold karat can be showed directly.
5. It's suitable for solid metals with no precious stones.
6. Based on the marketing demand, special software was designed. The value of "HI" and "LO" can be set by users freely. It will show "HI" when the value is higher than upper limit, and show "LO" when the value is lower than low limit.
7. It can be used for testing the density of other precious metals, such as silver, copper, tin and so on. And it also can be used as general weighing balance.
