Multi Tester III Presidium

A pocket-sized instrument that instantly identifies diamonds and moissanites based on their thermal and electrical properties. The Presidium Multi Tester III is the only instrument needed to verify the authenticity of diamonds against moissanites, cubic zirconia, and other diamond simulants. Showcasing a new ergonomic design with a rubberized anti-slip grip, PMuT III promises greater ease of handling during testing. Presidium’s Multi Tester is the world’s first tester that tests for both diamonds and moissanites in a single instrument. Its measuring probes and electronics circuitries detect data from the gemstone being tested via a customized micro-controller, identifying diamonds and moissanites based on their thermal and electrical properties. PMuT III has a retractable probe tip that ensures consistent pressure against the gemstone during testing for more reliable results. With the industry's thinnest probe tip size of 0.6mm, PMuT III tests diamonds as small as 0.02ct.
