 A large range of gold purity k-number tester uses Archimedes drainage method to quickly test the density, volume and purity of various metals, alloys and K-gold. The density bracket is cast by one-piece aluminum, and the test value is more stable and faster! It is suitable for density test of gold, platinum, K gold, precious metal, tungsten alloy, zinc alloy, etc

Product advantage:


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.Japanese original host, stable performance, accurate measurement


3.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) .


4.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.


5. With the mixture proportion function, it can test other precious metals, such as: platinum, silver, palladium, copper, rhodium...and so on


6.Adopting a light and thin stainless steel can reduce the error caused by the buoyancy of the wire.

7. Adopting the design of big tank, it can decrease the inaccuracy caused by supporting wire's buoyancy


8. Only applicable to solid metal sample which can be inlayed with gem stones . It can also be used as a precision electronic balance.


9.It has the function of actual water temperature compensation to avoid the deviation of measurement results caused by different water temperature


10.Built in rechargeable battery, equipped with wind shield, more suitable for field test


11.With RS-232C communication interface, convenient to connect PC and printer, xf-68 printer can be selected to print measurement data



Application fields:

 Pawn shops, precious metal recycling, jewelry silver buildings, banking, mining, jewelry manufacturing plants, jewelry testing centers, industries, gold and precious metal research laboratories and other industries


Measurement procedure:

Step 1:
Place gold on test board to measure weight in air,and then press MEMORY key button to memory.

Step 2:
Place the gold into water to measure weight in water,and then press MEMORY key button to memory. Density value is displayed.
