Electronic Gold K Value Analyzer, Gold Karat Purity Testing Machine DH

Application
Pawn broking, bank, jewelry shop, precious-metals recovery, jewelry factory, gemstone testing center,precious metals researching.etc.
In accordance with archimedes principle water buoyancy method, GB/T1423 of precious metals testing standard,and so on.
K value of gold,PT value of platinum,density value,purity percentage can be measured.
Features
a)Quickly measure the purity of gold,platinum,and other precious metals.Distinguish if the object is fake or genuine. b)No damage testing, cleaning and environmental protection. c)Measuring just need 10 seconds,convenience,stabilization,and accuracy. d)Multi-mode,gold mode,platinum mode,other precious metals mode can be shifted. e)Multi-function;the purity of other precious metals can be measured.such as tin,copper,silver.etc.also it can be used as precision balance. f)Function of top and bottom limitation,it can display OK,HI,LO in the state of qualified,exceed,less.Prompt alarm. g)Function of automatic zero tracking,buzzer warning,and overload warning. h)Function of solution compensation.Either water or other liquids can be used as medium. i)Adopt the completed high-capacity measuring accessories with the transparent injection mould tank,which can resist wear,fall off,and corrosion. j)Adopt the completed special wind and dust cover,which makes the structure convenient and durable. k)Interface of RS-232C is included.the printer of DE-40 will be available to connect PC with machine.
