A handy desktop device developed to estimate the purity of gold alloys from 8K – 24K, in a safe and precise manner.

Presidium Gold Karat Tester (PKT) is the first of precious metal testers from Presidium, and uses electrochemical effect to estimate the purity of gold in the unit of Karat, through an easy-to-use format.

It is a useful tool to have, as the testing liquid is optimally ejected through a motorized dispenser pen, which also enhances the precision of this device. Activated by a simple push button on the dispenser pen, this allows the liquid to be safely dispensed in a uniform and optimum quantity each time, achieving consistent results.

The PKT identifies the karat of both Yellow and White gold, platinum and can indicate if the material is non-metal. It tests across a range of different types of gold jewelry including brooches, earrings, necklaces, rings, etc.
