Description
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..The purity of gold,platinum,and other precious metals can be measured in a short time.; Multi-mode,gold mode,platinum mode,other precious metals mode can be shifted; Interface of RS-232C is included.Maximum weight: 300g; Weight resolution: 0.005g; Multi-function; the purity of other precious metals can be measured.such as tin,copper, silver., etc. also can be used as precision balance.Density resolution: 0.001g/cm3; Measuring time: 15S; Function of top and bottom limitation;it can display"OK,HI,LO" in the state of qualified, exceed, less; Prompt alarm.; Function of automatic zero tracking,buzzer warning,and overload warning.Combine archimedes principle with micro electronic technique; the purity can be calculated through measuring density of precious metals.features of no damage on sample; simple operation,fast and accurate Measurement Procedure: a)Measure the gold weight in air,and then press the ENTER button to memory.; b)Place the gold into water to measure the weight,and then press the ENTER button to memory.show the K value of gold,purity percent,density value
