Hardness Identification Crystal Tool Thermal Conductivity Meter Drill Pen Instrument Detection Diamond Authentic

Features:

1. High accuracy: the indicator light can be adjusted according to the temperature of the environment and the weight of the product being identified, which will make the measurement result more accurate.

2. Identify the true and false of diamonds: the thermal conductivity meter is an electronic instrument designed and manufactured according to the thermal conductivity of diamonds to identify the true and false of diamonds.

3. Precision electronic instrument: this instrument is a precision electronic instrument, the use environment is 5-35 degrees Celsius, and the air relative humidity is 80%.

4. Easy to use: turn on the power switch, the power indicator light is on, the instrument starts to warm up, and after a few seconds, the standby light is on and the instrument can be used.

5. Portable electronic devices: it is used to distinguish between real diamonds and other simulated g, go shopping with it, and no longer have to buy counterfeit diamonds.

Descrtions:

This thermal conductivity instrument is an electronic instrument designed and manufactured according to the thermal conductivity of diamonds to identify the true and false of diamonds.

Notes:

1.When the temperature is lower than 10 degrees or higher than 35 degrees, it can not be accurately measured.

2.Detection is more accurate in windle and dustle environments.

3.Ensure that the surface temperature of the tested object is consistent with the indoor temperature.

4.The surface of the object to be tested should be clean. Oil stain. Waxing. Impact detection of semi-finished products

5.Use gla to calibrate before each test and test after each test.

6.Surface neatne ensures that the probe is in full contact with the detected object at 90 degrees perpendicularity

7.The hardne is 5.5 or 6 if it appears to jump between, for example, 5-6 after testing.
