Presidium Gold Karat Tester

Presidium has engineered a high quality and reliable gold tester in the Presidium PTK Gold Karat Tester that sets a new standard for ease of use and efficiency in gold testing.

All electrochemical gold testers use a solution delivered in a pen device and the Presidium PTK uses the same basic system. Presidium PTK has  improved on the pen by making the application of test liquid automatic, so that with every test you get just the right amount of solution to do the job.  The Presidium PTK also includes a built-in calibration pad, so you no longer have to have a separate calibration gold to do this important and necessary step for accurate testing.
