1.Suitable for:

• Jewelry industry, Bank, Pawn industry，Gold and Precious Metal research lab.

• According to the buoyancy method of Archimedean principle, can show gold karat, density and purity%rapidly and accurately.

4.Functions:

• Only two weighing steps, karat, density and purity of gold can be showed rapidly and accurately.
• With the mixture proportion function, it can be used for testing density and purity of platinum, silver and other metals.
• With the special software design, it can directly and circularly show the gold karat (including gold-copper-silver,gold-silver, gold-copper), gold purity%(including gold-copper-silver,gold-silver, gold-copper)
• With the function of HI and LO limit, the wide karat range from 9K to *4K and the LO value can be set freely.
• No stains and scratches left on gold after testing, it doesn't need to use the sulfuric acid solution or test the standard samples.
• Pure water or distilled water can be used as testing medium, it is low cost and easily got.
• By adopting the design of big tank, it can decrease the inaccuracy caused by supporting wire's buoyancy.
• Can't test hollow samples and the samples with precious stones; it can be used as general balance.
• Standard size of water tank: **0X**0X*0㎜.
