Principle: According to the buoyancy method of Archimedes, can read

the gold karat, density and purity% rapidly and accurately.

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.

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.
