Applicable to: jewelry industry, banks, pawn shops, gold and precious metals research laboratories.
Principle: According to Archimedes principle buoyancy method, accurate, fast reading gold K number, density and purity, and precious metal mixing ratio.

1, can quickly and accurately determine the purity of precious metals, density (specific gravity) and the number of gold K, only two weighing steps;

2, after the measurement will not leave any traces and pollution, without the use of sulfuric acid solution or test the standard sample;

3, the coating thickness> 30μm above the Brazilian fire gold can also be easy to determine;

4, by the special software design, can be directly circulated to show the different elements of the gold K number (including gold and silver, gold and silver, gold and copper), gold purity (including gold and silver, gold and silver, gold and copper);

5, according to market demand, the special software design, the user can set the gold K number of the upper and lower limits, when the test gold K number greater than 24K, the instrument will show HI; less than 12K, will show LO, to more Intuitive, faster way to identify the authenticity of gold;

6, with a mixing ratio function, can test the mixing ratio of other precious metal alloys. Such as: platinum, silver, palladium, copper, rhodium … and so on;

7, the use of one-piece forming a large transparent tank (size: 15cm × 10cm × 9cm), the use of special materials into the sink mold, not only anti-wear, corrosion resistance, and easy to break, but also very beautiful, can greatly facilitate the user’s use;

8, the use of lightweight, thin, stainless steel hanging line design, can greatly reduce the buoyancy caused by the bucket line error;

9, with a standard RS-232 interface, you can connect the printer and computer output test data.
