Diamond Tester II
There are 2 kinds of sounds and 3 kinds of color lights, so it is easy to identify the true and false diamonds. Comes with leather case and a battery.
Technical characteristics:
1. Pocket Handheld.
2. NDT, easy and accurate operation.
3. Working power supply: DC9V battery.
4. Boundary dimension: 160 * 40 * 22MM Weight: about 110g
Operation method
1. Turn on the power supply, the power indicator is on, and the instrument starts to warm up. The instrument can be used in a few seconds.
2. Put the tested bare drill into the appropriate hole of the support tray, and put its table top upward. The inlaid ones do not need to be placed in the tray hole, but can be held by hand.
3. Several light emitting diodes are turned on according to the weight of the real and fake diamonds and the temperature of the measurement site.
4. Remove the probe sheath, and touch the conductive plate on the back cover of the instrument with the hand-held instrument and the index finger of the right hand; Make the probe vertically and slightly contact the table top of the real and fake diamonds to be measured.
5. Pay close attention to the reflection of the instrument. If the remaining yellow LED lights up, when it lights up to 9 diodes, and the buzzer sounds, it indicates that the subject is a real diamond. On the contrary, if less than 9 lights up and the instrument does not emit a beep, it indicates that the diamond is fake or counterfeit.
