300g Precious Metal Tester / Water Gold Testing Machine 3000g/0.01g Percentage

Understanding Karats:

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.

Application:

pawnbroking,jewelry industry,banking industry,jewelry testing center,mining industry,precious metal recycling,precious metal materials researching laboratory.,etc.

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.

Measuring Type:

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.

Notes:

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

Features:

• Distinguish whether the gold,karat gold,platinum,silver,other precious metal is the genuine or not.
• Test the purity of gold,karat gold,platinum,silver to confirm if the marked content is correct or not.
