AN INDUSTRY LEADERThe Gem Tester II is based on the invention of Professor Julian Goldsmid from the University of New South Wales in Australia. It was developed to distinguish between diamonds and its other simulants using the principles of thermal conductivity.The Gem Tester II with Assisted Thermal Calibration provides a quick and easy way to identify diamonds/moissanites and separates up to 16 common colored gemstones based on their thermal conductivity with its clear and direct analog display.NEW INCLUDED CALIBRATION FEATUREAs PGT II works on the thermal conductivity of the gemstone, its measurement will be affected by the testing environment. WIth the improved function of Assisted Thermal Calibration (ATC), the user is now able to easily calibrate the tester according to the testing environment for a reliable and consistent reading.The Gem Tester II Features:Retractable thermoelectric probe tip that ensures constant pressure between probe tip and gemstoneIndustry's thinnest probe tip (0.6mm) for testing diamonds as small as 0.02ctMetal alert buzzer to ensure that probe tip is in contact with gemstone during testingClear and easy-to-read analog dialNo waiting time between testsBuilt-in Calibration (CAL) and Glass test discs for referencePowered by 2 x AA batteries or adaptorIncluded in Your PackagePresidium Gem Tester IIRetractable probe penBuilt-in Calibration (CAL) and Glass test discsAC adaptorUser handbookWarranty cardProtective carrying case
