DH-900K Precious Metal Purity Tester
Please be noted that the machine has limited function which is determined by its' principle.
Following gold type can NOT be tested:
(1)gold has any decoration.
(2)gold has the painting.
(3)gold inside is hollow.
(4)plating gold.
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.
Combine Archimedes principle with micro electronic technique and adopt sensor imported from Germany,the purity can be calculated through measuring density of precious metals.It has the features of no damage testing,simple operation,fast and accurate.
K value of gold,PT value of platinum,density value,purity percentage can be measured.
