Machine Advantages

1. The use of Archimedes' principle to measure the density and specific gravity of gold jewellery is a quick and accurate method for the identification of gold jewellery. It does not damage the gold jewellery, so as to better protect the gold being tested. It is the most widely used gold purity testing instrument in the pawn industry.

2. It adopts the original imported sensor from Germany HBM. The measurement is stable and accurate.
