2201K Touchscreen Gold Purity Tester, 220 g Capacity and 0.0001 g/cm³ Resolution (CAT#: STEM-BC-4065-ZJF)

The 2201K is a precision touchscreen gold purity tester for solid precious-metal samples. It calculates density through Archimedes water-displacement measurement. The instrument is designed for jewelry, banking, pawn, and precious-metal laboratory applications. Its 220 g capacity combines moderate sample handling with high density resolution. The large LCD presents measurement results clearly and directly. Temperature and liquid-medium compensation can be set according to the selected procedure. Density upper and lower limits support rapid compliance judgment. An integrated buzzer provides audible status indication. RS232C communication, a rechargeable battery, and a draft shield improve data management and field reliability.
