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. Features Retractable thermoelectric probe tip that ensures constant pressure between probe 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 Catered to both left-handed and right-handed users alike International voltage compatibility Low batter indicator Automatic power off Protective carrying case included Optimal Operating Temperature: 18°C – 27°C (65°F – 80°F)Storage Temperature: 10°C – 51°C (50°F – 124°F) Dimensions and Weight Length: 165mm (6.5 inches) Width: 25mm (0.98 inches) Height: 40mm (1.57 inches) Weight: 97g Power and Battery 3 x AAA batteries (approximately 7 hours of continuous use) Technical Specifications Dimension: 165 x 40 x 25mm (6.5 x 1.6 x 0.96in) Weight: 97g (0.45lb) Power: 3 x AAA batteries Battery Life: Up to 3 hours of continuous use based on alkaline batteries Standby Time: 10 min from the last measurement Operating temperature: 18°C-27°C (65°F-80°F) Storage temperature: 10°C- 50°C (50°F-122°F)
