II. About the Presidium Gold Karat Tester
The Presidium Gold Karat Tester (PKT) is an instrument
that estimates the different purity of gold alloys in the unit
of Karat, using an electrochemical effect. Based on this
methodology, gold alloys of different gold purity can be
ascertained upon its reaction with a prescribed electrolyte,
at pre-set electrical conditions.
The PKT is revolutionary in that it has enhanced precision
through the use of a mechanical motor in the dispenser
probe pen that dispenses the optimal amount of electrolyte
(i.e. testing liquid) accurately and safely, hence producing
consistent results when testing on gold.
The device is capable of identifying the content of alloy
ranging from 8 karats to 24 karats, and for both yellow
and white gold. It can also identify platinum and detect
non-gold metals.
The Presidium Gold Karat Tester (PKT) features the
following:
• Able to identify the karat of
◦ Yellow gold - 8k to 24k ◦ White gold - 8k to 24k
• Identifies platinum
• Detects other non-gold metal (i.e., silver, aluminium,
copper, etc) by indicating “Not Gold”
• Clear quality LED display screen
• Push button on the probe pen for easy testing and calibration
• Calibration disc to always ascertain accuracy of the device
• Stylish ergonomic design
• Testing time of less than 40 seconds
• Automatic power-off after 10 minutes of inactivity when
on alkaline batteries
• Up to 200 tests per refill
