Overview

OTi by Presidium revolutionizes diamond authentication with its dual Optical/Thermal testing in a single probe, ensuring accurate distinction between natural and synthetic diamonds. It is a quick, cost-effective tool that ensures accuracy and trust. 

Using OTi by Presidium

OTi by Presidium is a portable diamond verification instrument for loose and mounted stones designed to separate natural diamonds from synthetic diamonds and diamond simulants. 

OTi has a dualprobe tip that measures thermal conductivity and UV light absorption to determine stone type. 

OTi is manually operated but gives an automated result on its built-in display.

When using the device, the probe tip should be held at an upright position 90 degrees perpendicular to the table of the gemstone. 

The user then fully depresses the tip applying constant pressure for the duration of the testing bar shown on the display. 

User must always ensure the probe tip is kept clean; when necessary it should be cleaned as per the procedure in the supplied User Manual.

The instrument makes a measurement and displays one of the following results:

i) Diamond (single beep)
ii) CVD/HPHT/Type IIa (single long beep)
iii) Moissanite (double beep)
iv) Simulant (no beep)
