CE,FCC Certification!Warranty for Two Years!!!

DH-300K.High Precision Gold Tester Jewelry Tool,Portable Electronic Gold Tester

Application：典当砖，银行，珠宝店，珍贵金属回收，珠宝厂，宝石测试中心，贵金属研究。etc。

In accordance with archimedes principle water buoyancy method, GB/T1423 of precious metals testing standard,and so on.

Combine archimedes principle with micro electronic technique;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.
