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

2. No stains and scratches left on yourgold after testing, it doesn’tneed to use the sulfuric acid solution to test the standardsamples.

3. It can easily judge thealloys with the metallic-membrane plating of more than 30μmthickness.

4. With the special software design, it can directly andcircularly show the gold karat (including gold-copper-silver,gold-silver, gold-copper), gold purity%(includinggold-copper-silver, gold-silver, gold-copper)

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

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

7. It has the RS-232Cinterface, 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 solidmeasuring), this can decrease the inaccuracy caused by supportingwire’s buoyancy.

9.Can’t test the samplesinlaid precious stones and hollow samples. It can be used asgeneral balance.
