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.

1. Four operation modes: constant current operation; constant voltage operation; constant power operation; constant resistance operation2. This time, a flexible input wiring port design is adopted. Users can manually connect different adapters to achieve different measurement functions to extend the functions3. Automatically generate measurement data reports, stop voltage and time-limited discharge4. First turn off the load switch "OFF", measure the current battery no-load voltage, and then turn on the load switch "ON" through the setting key. At this time, you can read the internal resistance parameters of the current battery. The internal resistance of this table is calculated by the formula: (no-load voltage-load voltage)/current current=battery internal resistance5. Long press the setting key, and then short press the setting key when it flashes to switch to time-limited discharge for timing setting to obtain the effect of worry-free discharge aging. The time-limited discharge can be set to count down for any length of 1-99 hours and 59 minutes. When the set time is reached, the discharge will automatically stop. It can be used as a timer to turn off the constant current discharge aging functionReal-time display of internal and external dual temperature measurement data, three intelligent safety protections6. Test various USB data cables/chargers. First, use a data cable to connect the corresponding interface of the load device, and then use the DC power cable and Android cable to connect to the "Micros input detection port". Then adjust the current by setting the button to detect the voltage drop of the data cable and the performance stability of the charger.7.
