Technical Information for the Golden Touch Electronic Gold Tester

The gold is tested through an electromagnetic molecular process using electrically charged metal plates. A positively charged clip is connected to the tested jewelry, while the metal plate under the strip is negatively charged. When the tested jewelry comes in contact with the impregnated test strip, gold atoms are transferred to the strip. There will be no reaction to other metals. The amount of gold transferred to the strip is minuscule.

How to test if an item is solid gold or plated:
At Test Position, touch the edge of the jewelry to the strip, hold it for 2-3 seconds and then slide it slowly across the test strip. If the jewelry is gold, between 6-24K, a visible light-brownish line will continue all the way across the strip. If the jewelry is gold-plated, you will see only a very small brownish spot or short line. The length of the line will depend on the thickness of the plating. Pure gold and high karat gold will leave a beautiful orange-yellow colored line. 18 karat and under will leave a brownish line, and a dark brown line will show for the lower grades. But the coloring of the lines is not necessary to know the grade.

To establish the grade of the gold:
Using the rotary switch will help you establish the karat grade. First, turn the dial to a higher grade setting and test the gold. Gradually decrease the dial's grade setting until a line is made. The grade setting at which you see the first continuous line will be the grade of the gold. For example, 14K will not leave a line on 22 or 18K but it will leave on 14K, as well as the lower dial settings. Read and follow the instructions carefully.

Test Strips:
The test strip is non-toxic and long-lasting. Even after a long period of time, it can continue to be used for testing. We recommend that the strips are kept in the accompanying plastic box for longer usage and better results. The marks on the strip will disappear in a few hours, and it can be reused on both sides. Additional packages of 50 test strips strips can be supplied by request on the order form.

The Golden Touch gold tester is very simple to operate. No previous knowledge of electronics is necessary, provided you follow instructions carefully and spend a short time practicing to become familiar with the functions.

The tester has been adjusted according to the USA gold standard.
