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. MH-300K 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. 

MH-300K 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.
