Crystal Tester Pen Thermal Conductivity Meter Drill Diamond Authentic Jade-Black-

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.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.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 used to distinguish between real diamonds and other simulated gems go shopping with it and no longer have to buy counterfeit diamonds.

Descriptions:
1.The gemstones must be clean dry and at room temperature.
2.Pocket portable handheld thermal conductivity instrument.
3.Non-destructive testing simple and accurate operation.

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 windless and dustless 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 glass to calibrate before each test and test after each test.
6.Surface neatness ensures that the probe is in full contact with the detected object at 90 degrees perpendicularity
7.The hardness is 5.5 or 6 if it appears to jump between for example 5-6 after testing.
