A gold density scale checks the purity of gold, silver and other precious metals without damaging them. It weighs the item in air and then in water (Archimedes’ principle); the density shows the karat and reveals impurities or hollow fills. HSCo’s gold density scale is a precision balance with a density kit inside a glass draft shield, in 300 g × 1 mg or 1,200 g × 10 mg versions, with an RS232 port for a computer or thermal printer.
Why jewellers and gold lenders use it

- Fast, consistent results for daily buying, selling and valuation.
- Precise weighing. 1 mg or 10 mg resolution.
- Records and printouts. An RS232 port connects a computer or thermal printer.

Questions buyers ask
The item is weighed in air and then in water. The difference gives its density, which matches a known karat for pure gold alloys.
No. The test is non-destructive.
300 g × 1 mg and 1,200 g × 10 mg.
Yes, through the RS232 port to a thermal printer, or to a computer.
