Presidium Gem Tester II (PGT II)
The Presidium Gem Tester II (PGT II) is a cutting-edge, laboratory-proven device designed to quickly and easily identify and distinguish up to 15 different types of gemstones. Whether you're a professional gemologist or a hobbyist, this compact and portable tool delivers reliable results with minimal effort.
Functionality
The PGT II utilizes an advanced thermoelectric probe that measures the thermal conductivity of any gemstone, whether loose or mounted. The specially calibrated scale indicates the unique thermal properties of the stone, making it irrelevant whether the surface is polished or unpolished. This functionality is based on the scientific principle that gemstones conduct heat at varying rates.
Calibration and Testing
Calibration is streamlined and automated, requiring just a few minutes. Integrated test discs within the frame simplify the process, eliminating the need for manual adjustments or potentiometer tuning. The retractable test probe ensures consistent pressure and is ultra-thin (0.6 mm), allowing for the precise testing of gemstones as small as 0.02 carats.
Test Procedure
- Warm-Up: A quick 20-second warm-up phase prepares the device for use.
- Testing: Place the probe on the gemstone, and results are displayed within approximately 2 seconds.
- Metal Detection: A built-in detector alerts you if the probe accidentally touches the metal setting instead of the gemstone.
Convenience and Portability
This lightweight unit is powered by the included 110–220 V adapter or 2 AA batteries (not included), making it ideal for both on-the-go and stationary use. A protective carrying case is included for added convenience and safety.
Specifications
- Dimensions: 77 mm (H) x 75 mm (W) x 17 mm (D)
- Power Options: 110–220 V power supply or 2 AA 1.5 V batteries
The Presidium Gem Tester II is the perfect companion for anyone seeking accurate and efficient gemstone identification, combining precision technology with user-friendly design.
