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
