DH-900K Electronic Metal Tester With Factory Price In Testing Equipment
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;adopt sensor imported from Germany,the purity can be calculated through measuring density of precious metals.features of no damage on sample;simple operation,fast and accurate.
K value of gold,PT value of platinum,density value,purity percentage can be measured.
| Model | Density resolution | Maximum weight | Weight resolution | Model |
| DH-900K | 0.001g/cm3 | 900g | 0.01g | Gold,platinum |
1. Just two simple steps,the purity of precious metals and gold karat can be showed rapidly and accurately.No stains and scratches left on gold after testing. Needn't use the sulfuric acid solution to test the standard samples.
2.The gold K number and density, platinum Pt value and density can be accurately measured in only 5 seconds.Directly and circularly show the gold karat (including gold-cop.per-silver, gold-silver, gold-copper), gold purity%(including gold-copper-silver, gold-silver, gold-copper) .
3.More intuitive and more rapid to identify gold authenticity. It adopt special software design according to market demand which enable users to set the upper and lower limits of K number and Pt value.When the K value of testing gold is more than 24K, the instrument will display HI. When K value less than 12K, LO is displayed.
4. With the mixture proportion function, it can test other precious metals, such as: platinum, silver, palladium, copper, rhodium...and so on
5.Adopting a light and thin stainless steel can reduce the error caused by the buoyancy of the wire.
6. Adopting the design of big tank, it can decrease the inaccuracy caused by supporting wire's buoyancy
7. Only applicable to solid metal sample which can be inlayed with gem stones . It can also be used as a precision electronic balance.
8.Widely be used in jewelry industry, gold and precious metals research lab, jewelry shop, bank, pawn shops .
Measurement Procedure
a)Place sample on testing board to measure weight in air,press ENTER key to memory.
b)Place sample into water to measure the weight in water,press ENTER key.the K value of gold,purity percent,density value will be displayed.
