1. Only two weighing steps, the purity% of precious metals and gold karat can be tested rapidly and

accurately.

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

3. It can easily judge the alloys with the metallic-membrane plating of more than 30μm thickness.

4. 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)

5. With the function of high limit and low limit, the wide karat range from 9K to 24K and the data of HI and LO can be set freely.

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

7. It has the RS-232C interface, can easily connect to the PC and the printer.

8. It adopts design of tank (the maximum dimension of the sample is D100×W70×H25mm for solid measuring), this can decrease the inaccuracy caused by supporting wire's buoyancy.

9. Can't test the samples inlaid precious stones and hollow samples. It can be used as general balance.
