1. Only two weighing steps, karat, density, and purity of gold can be shown rapidly and accurately. 

2. With the mixture proportion function, it can be used for testing the density and purity of platinum, silver, and other metals.

3. 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)

4. With the function of HI and LO limit, the wide karat range from 9K to 24K and the HI and LO value can be set freely.

5. No stains and scratches left on gold after testing, it doesn’t need to use the sulfuric acid solution to test the standard samples.

6. Pure water or distilled water can be used as the testing medium, it is low cost and easily got.

7. By adopting the design of a big tank, it can decrease the inaccuracy caused by the supporting wire’s buoyancy.

8. Can’t test hollow samples and the samples with precious stones; it can be used as general balance.
