1. Material: plastic + alloy probe2. 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 specially 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 a buzzing sound is made when it touches the surface of the diamond5. Whether it is to identify the authenticity of diamonds or test the hardness of jade, it should be noted that the probe of the thermal conductivity meter should be at a 90-degree right angle to the object being tested6. When testing, adjust the three-color indicator light to the 4th grid, then press the triangular iron sheet at 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 above, that is, the red light area, and a dripping sound is made; if it is to test jade, the light will light up the 6th or 7th grid, indicating that the hardness of the jade has reached, and there will be no sound7. The operating environment is 5-35 degrees Celsius, and the tested product must be clean, dry and at room temperature8. Dimensions: 41x155x21 mm9.
