Digital Gold Density Meter, Precious Metal Tester

The digital gold density meter offers fast, accurate testing of precious metal purity and gold karat values. With advanced software and a large water tank design, it ensures precise results without damaging samples. Ideal for gold, silver, and alloys, it’s perfect for professional jewelers and metal testing.

Feature:

• Quickly and accurately determines the purity (%) of precious metals and the gold karat value with just two weighing steps.
• Leaves no traces or contamination after measurement; no need for sulfuric acid solutions or standard test samples.
• Can easily identify Brazilian fire-gold with a coating thickness of >30 μm.
• Special software design allows direct cycling display of gold karat values and gold purity (%) (gold-copper-silver, gold-silver, gold-copper).
• The approximate karat range is from 9K to 24K.
• Features a large water tank design to reduce errors caused by the buoyancy of the hanging wire.
• Cannot test gemstone-mounted or hollow samples. Can also be used as a general balance.
