Portable Diamond Testing with THERMAL CONDUCTIVITY and REFLECTIVITY measuring in the same Affordable instrument!! Double the confidence in testing for diamonds against all known simulants, including Synthetic Moissanite!!
The PRESIDIUM DUOTESTER is the only tool on the market that provides the user with two proven tests for diamonds and the ability to differentiate between similarly colored gemstones. The easy-to-read dial of the DUOTESTER is calibrated to indicate the differences in thermal conductivity of the most popular gemstones and simulants. Simply touch the tip of the thermal conductivity probe pen to a mounted or loose stone. Diamond is easily identified by any reading in the green area of the dial, and colored gemstones can be easily differentiated from one another by the clearly labeled zones provided in the red area. Even coated gemstones can be accurately tested.

DIGITAL REFLECTIVITY MEASUREMENT
Diamond and its simulants reflect light proportionally to their respective refractive index. The PRESIDIUM DUOTESTER provides the user with a digital reflectivity meter and an easy to use Simulant Reflectivity Chart. The reflectivity number from the meter is simply cross-referenced with the chart to identify the stone. An unknown gemstone can be tested for its thermal conductivity and, if necessary, the results can be confirmed with a quick and simple reflectivity test. All stones indicated as diamond by the thermal tester should be tested with the reflectivity meter to test for Synthetic Moissanite, thus providing double the assurance for the same price.

Please note, that the digital reflectivity meter operation is similar to operation of optical refractometer, thus testing of mounted stones may be difficult or impossible. Mounted gemstones could only be reliably tested if no part of metal setting is located above stone facet being tested (normally the table).

Convenience
The thermal probe pen includes a metal warning detector that emits a audible buzz if the gem mounting is accidentally touched. The DOUTESTER can be powered by 5 AA alkaline batteries or by the electrical adapter provided.
