<p><span>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. </span>Using dual technologies of Optical and Thermal in a single probe, the Presidium OTi distinguishes between Natural Diamond and Lab-Grown CVD/HPHT as well as Moissanite, CZ, and Simulant. Extremely accurate, the OTi tests all proportionally cut diamonds from .06cts in the color range of D to J with a minimum table size of 1.6mm.</p> <p><span style="text-decoration: underline;"><strong>FEATURES:<br /></strong></span></p> <ul> <li>User-safe function to shut off UV light when not in use</li> <li>Resistive Touch Screen</li> <li>Auto Shutdown Feature</li> <li>Low Battery Indicator</li> <li>6 Languages user interface</li> <li>Stylish ergonomic design for portability and ease of use</li> </ul> <p class="title right-border"><span style="text-decoration: underline;"><strong>BENEFITS:</strong></span></p> <ul> <li>Help identify colorless diamonds against CVD/HPHT lab-grown colorless diamonds, all types of moissanite and all common diamond simulants such as Glass, Sapphire and Cubic Zirconia (CZ)</li> <li>Dual technologies of Optical/Thermal in a single probe for instant results</li> <li>Test on loose and mounted diamonds in all jewelry settings</li> <li>Replaceable Probe Technology to minimize equipment downtime</li> <li>Compact and portable design for on-the-spot testing</li> <li>Test on colorless polished diamonds of all proportional cuts with a minimum gemstone's table width of 1.6mm</li> </ul> <p><span style=&q
