The design of this Gem tester is based upon the use of heat conductivity to distinguish diamond stimulants from diamonds. It incorporates a sophisticated thermoelectric probe and a thermometer which ensures reliable readings. This unit can be used on mounted or unmounted stones, which can be as small as 0.02 carat. Includes an ac adapter, a soft vinyl pouch and a hard plastic case. One-year factory warranty.
This unit utilizes proven thermal conductivity testing method to instantly verify the authenticity of diamonds. The test results are indicated by visual light and audible beeps. Operates on alkaline (AAA) batteries (not included) or AC adapter, 120 volts, (not included). One year factory warranty. Features include: no waiting between tests, pocket size, low-battery indicator, carrying case, metal detector-intermittent beep, measured diamond-continuous beep, metal detector-intermittent beep and low battery consumption.
