Feature:

*  brand new and high quality

*Thermal conductivity meter is based on the thermal conductivity of diamonds designed and manufactured

 specifically for the identification of genuine-and false diamond an electronic instrument.

*The instrument for precision electronic equipment, the use of the environment for the 5-35 degrees Celsius, air relative humidity at 80%.

*The gemstones to be tested must be clean, dry and at room temperature.

*Pocket portable handheld.

*With LED light and audio result indication.Accurate and reliable reading, with metal-alert, testing platform for loose stones.

*Non-destructive testing, simple and accurate.

*This is Electronic Diamond Tester a portable electronic device for distinguishing real diamonds from other simulated stones.

*It is designed for quick, precise, and safe diamond testing, simple calibration for stones of various sizes.

Specifications:

*Working power: DC9V battery.(not included)

*Overall dimensions: 160*40*22mm

Instructions:

*Open the thermal conductivity meter power supply, the probe heating, generally takes 20 seconds.

*The hot needle touches the sample surface, according to the thermal conductivity of the instrument can determine whether the signal is diamonds tested samples.

Notice:

*DIAMONDS

 1. Beeping sound (beep-beep-beep)

 2.(1)1~4 of the Red Lamp box OF the Level Meter,(2)will light on.

(More no. of Red Lamp boxes will light up for bigger sized stones.)

*DIAMOND SIMULANTS(Except Synthetic Moissanite)

 1. No Beeping sound.

 2. No Red Lamp boxes will light on. Green and/or up to Yellow Lamp boxes may light on depending on the type of simulants.)

*METAL ALERT

 1. Continuous buzzing sound.

(The thermal conductivity of the metal is very high and can give the same indication as a Diamond with most Thermal Probes.

The Diamond Selector II has a Metal Alert buzzer to warn you when the Probe tip touches metal.)

If you hear the Metal Alert buzzing sound. re-touch the Probe tip so as to touch only the tested stone.
