DahoMeter 3 Years Warranty Digital Electronic Gold Density Tester Gold Purity Testing Machine Excellent Quality
Application:pawn broking, bank, jewelry shop, precious-metals recovery, jewelry factory, gemstone testing center, precious metals researching, etc..
In accordance with Archimedes principle water buoyancy method, GB/T1423 of precious metals testing standard, and so on.
Combine Archimedes principle with microelectronic technique and adopt sensor imported from Germany, the purity can be calculated through measuring density of precious metals. Features of no damage on sample, simple operation, fast and accurate.
K value of gold, PT value of platinum, density value, purity percentage can be measured.

Standard accessories:
Host, tank, test board, tweezer, thermometer, weight, wind and dust cover, a set of measuring particle parts, a set of measuring floating body parts, power transformer
Very important!!!
Due to the limited function determined by the principle.
Following gold type can’t be tested by gold density meter.
(1) Gold has any decoration.
(2) Gold has the painting.
(3) Gold inside is hollow.
(4) Plating gold.
Following gold type has high requirement for the operation:
(1) Gold with a complex structure
Here are some examples as following. We would not like to recommend you to test this kind of gold by using the gold density meter.
