Suitable for: Jewelry industry, Gold and Precious Metal research lab, Jewelry shop, Bank, Pawn industry
Principle: According to the buoyancy method of Archimedean principle, can read the gold karat, density and purity% rapidly and accurately.
Functions：
- Only two weighing steps, the purity% of precious metals and gold karat can be tested rapidly and accurately.
- 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.
- It can easily judge the alloys with the metallic-membrane plating of more than 30μm thickness.
- 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)
- 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.
- With the mixture proportion function, it can test other precious metals, such as: platinum, silver, palladium, copper, rhodium…and so on
- It has the RS-232C interface, can easily be connected to the PC and the printer.
- Can’t test the samples inlaid precious stones and hollow samples. It can be used as general balance.
