Presidium Gem Indicator (PGI)

The Presidium Gem Indicator is the only handheld tester in the industry specifically for

colored gemstones. It indicates up to 31 different types of colored gems based on their

thermal conductivity and even features a color input function that allows users to select

from a range of 12 common colors, thereby achieving more accurate results. With an

easy-to-read clear digital LED screen, this smart thermal tester also comes with the

Presidium patented refined changeable probe tip, which ensures minimal equipment

downtime.

The Presidium Gem Indicator is an enhanced and more convenient handheld version

of the Presidium Gem Tester/Colored Stone Estimator. It distinguishes

between diamonds and other colored gemstones using thermal conductivity.

The Presidium Gem Indicator probe consists of two linked thermometers; one which

is heated electronically, while the other is cooled by the gemstone being tested.

The difference in temperature creates an electrical output, which is then amplified

and displayed on the new digital LED display.

It is simple to use, easy to maintain and quick in giving you intelligent results about

your colored gemstones.
