300g NEW Design Electronic Digital Water Gold Tester Machine , Water Gold Testing Machine
Since gold is a soft metal, it’s often combined with other harder metals when it’s used in jewelry to provide durability. In general,gold is mixed with silver and copper(Except 24K pure gold).Gold jewelry is measured in 24 parts, called karats (K), to indicate how much of the piece is pure gold. So, if gold is 24K, all 24 parts of the jewelry are gold. Jewelry marked 22K is 22 parts gold, two parts harder metals.which means,the jewelery including 22/24(91.67%) gold,the remaining 2/24(8.3%) belongs to copper-silver mixure,or copper,or silver.Thus, the lower the number, the less gold. As such, 24K gold is the softest, while 10K is significantly the harder.Our machine can test the K value,density,purity percentage for mixure gold-copper-silver,gold-copper,and gold-silver.for jewellery manufacturer,the ratio of gold-silver-copper can be set freely to get the exact K value,density,purity percentage.

These series instrument gold tester is the dramatic updating and upgrading products.Compared with other competing products,it has been focused on enhancing weighting resolution,simplified operation procedure and operation method,upgraded software application function,improved reliability of measuring result. offer respectively three content measuring model for gold,platinum,silver and one alloy measuring model;
No need to bundle samples.Following value can be displayed precisely and quickly with only two procedure:
(1) karat value,percentage content,density for gold
(2) PT value,percentage content,density for platinum
(3) S value,percentage content,density for silver
(4) percentage content,density for other alloy.
Precious metal.such as gold,Karat gold,platinum,silver.
Mixed metal or other alloy metal.
Jewelry materials.such as ring,necklace,bracelet,watchband,belt fastener,gold ingot,gold bar,statue,coin.,etc.
Please check the samples to be tested firstly when do testing:
(1). products of which inside is hollow
if the hollow is closed.water or other liquids can't get access into,the samples can't be tested
if the hollow is opened,water or other liquids can get access into,the samples can be tested
(2). products set with precious stones------can't be tested
(3). products of which the density is very close to precious metal------can't be tested
Measurement Resolution and Range:
(1) Measure the weight in air firstly,press ENTER button.
(2) Place the sample into water to measure weight in water.Press ENTER button.display result.
