KBD-300KY Platinum Purity, Gold Karat Tester

الوصف

1.Suitable for:

• Jewelry industry, Bank, Pawn industry，Gold and Precious Metal research lab.

• Most gold is the alloy of silver and copper excepting *4K (pure gold). For example, *8K gold includes *8/*4 (*5%) gold and 6/*4 (*5%) copper, or silver & copper or silver. Therefore *8K gold products have different densities according to their different ratios. KBD***0KY 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.
  KBD***0KY 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 *4K, and show LO when gold karat is lower than 9K.

4.Functions:

• The machine has two modes; one is for testing gold, the other is for testing platinum. Under gold mode, it can
• show karat,density and purity of gold; Under platinum mode, it can show purity% and density of platinum.
• It can be used for testing density of other precious metals, such as silver, copper, tin and so on. And it also can be used as general weighing balance.
• The operation is simple, only two weighing steps, the testing result can be showed directly.
• 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.
• No stains and scratches left on sample after testing.
• It's suitable for testing solid metals without precious stones.
• Standard size of water tank: **0X**0X*0㎜,Sample size can be tested:**0X*0X*5㎜.
