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

1. Gold Purity measuring mode–measuring gold purity.
2. Platinum purity measuring mode–measuring platinum purity.
3. Alloy purity and density measuring mode 1–measuring the other precious metal purity.
4. Alloy purity and density measuring mode 2–measuring the other precious metal purity.

1. With RS-232 & USB interface.
2. With Infrared temperature sensors can automatically detect water temperature and automatically compensate for water temperature.
3. Quick and accurate determination of precious metal purity% and gold K number, just two measurement steps.
4. No trace of contamination will be left after the measurement, no need to use sulfuric acid solution or test standard samples.
5. Special software design can directly display gold Karat number and purity% (including gold copper silver, gold silver, and gold-copper).
6. With the setting function of the lower limit of the Karat value, the Karat number can be set freely from 1 to 24K.
7. With the function of setting the lower limit of PT value, the PT value can be set freely from 1 to 1000.
8. With alloy purity measurement function, can test other precious metals. For example platinum, silver, palladium, copper, rhodium, etc.
9. Cannot test the samples with gems and hollows. Can be used as a general balance.
10. The large tank design is adopted to reduce the error caused by the buoyancy of the hanging rail. The size of the water tank is 148 × 100 × 85mm.
