Description
Description
2. Working power supply: 9V battery x 1 (not included)
3. The thermal conductivity meter is an electronic instrument designed and manufactured based on the thermal conductivity of diamonds. It is specifically used to identify the authenticity of diamonds. It is also suitable for detecting/identifying the hardness of genuine gemstones such as jade, jade, crystal, etc.
4. The metal tip of the probe is electrically heated and produces a buzzing sound when it touches the diamond surface.
5. Whether it is to identify the authenticity of diamonds or to test the hardness of jade, it should be noted that the probe of the thermal conductivity meter should be at a right angle of 90 degrees to the object being tested.
6. When testing, adjust the three-color indicator light to the fourth grid, then press the triangular iron sheet on the back with your hand and align the probe vertically with the test object. If it is a diamond, the light jumps to the 8th grid or higher, i.e., the red light zone, and a dripping sound is produced; if it is testing jade, the light will illuminate the 6th or 7th grid, indicating that the hardness of the jade has been reached, and no sound will be made.
7. The operating environment is 5 to 35 degrees Celsius, and the tested product should be clean, dry and at room temperature.
8. Dimensions: 41x155x21 mm
9. Net weight: 57 grams
