Gold purity tester by density (Archimedes’ principle): precision balance with density kit and glass draft shield, 300 g × 1 mg or 1,200 g × 10 mg, RS232 for PC and printer.
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
- Non-destructive testing. No scratching, acid or melting.
- 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.
