The Presidium Gem Tester is the fastest and easiest way to eliminate human error and save time in identifying colored gemstones. Simply touch the testers Thermoelectric Probe to the surface of any stone, and the dial will obtain the heat conductivity of the material and provide an accurate reading based on the proven method of thermoelectric testing. Presidium made this tester light, durable, and portable, giving you the protection you need against unauthentic gems where and when you need it. The sophisticated probe pen requires no warm up period and no downtime in between testing, making operation fast and accurate. Furthermore, operating this device is extremely simple and doesnt require any specialized knowledge or training.
The specially calibrated dial will show you the relative heat conductivity of the material, at which point the identity of the specimen can be easily distinguished with the Color Stone Estimating Function. As an added convenience, the tester uses a built-in metal detector that will alert the user if they have accidentally touched a mounting instead of the stone specimen. This tester minimizes human error and maximizes productivity, a reputation that many Presidium instruments have earned over time.
Operates on 2 AA batteries (not supplied)
