III. About your Presidium Multi Tester III 

The Presidium Multi Tester III has been developed to help 

distinguish between colorless diamonds and moissanite 

using the combined principles of thermal and electrical 

conductivity. 

The measuring probe with electronic circuitry is 

designed to detect and segregate data collected from 

the gemstones via a customized micro-controller. The 

information gathered will be displayed within seconds.

The Presidium Multi Tester III has been subjected to 

thorough and extensive laboratory tests, and will 

generally give a clear and reliable reading of the 

gemstone being tested under proper use. However, you 

are advised to conduct further supporting tests.

This tester was designed with the following 

objectives:

•    Help in the identification of diamonds and moissanite 

     with a single instrument;

•    Provide fairly consistent and reliable test results under 

     proper use; 

•    Enhanced ergonomic features, such as visibility of 

     test results, maximum grip comfort, ease of use and 

     portability.  

The Presidium Multi Tester III features the following:

•    Retractable thermoelectric probe tip that ensures 

     constant pressure between probe tip and gemstone

•    Industry’s thinnest probe tip (0.6mm) for testing 

     gemstones as small as 0.02ct 

•    Metal alert buzzer to ensure that probe tip is in contact 

     with gemstone during testing 

•    No waiting time between tests

•    Ergonomic design with rubberized anti-slip grip for 

     better handling during testing

•    180-degree multi-viewing LED display

•    International voltage compatibility

•    Low battery indicator

•    Automatic power off
