Specification :

The tester was made with a technological breakthrough that allows for the measurement of low to high karat gold products, assuring the buyer of gold content in the most critical gold alloys.

Its microprocessor-based technology allows the user safely and non-destructively determine gold content of alloys up to 24 karat in all four gold colors. Karat readings appear directly on LCD display.

The built in microprocessor makes testing simple when you follow the directions. Simply squeeze the special gel from the probe, select the color of gold you are testing, and obtain the reading in karats and percentage. Also reads " Platinum" and " Not Gold."
