precision electronic instrument designed and manufactured based on the thermal conductivity of diamonds, specifically used to distinguish the authenticity of diamonds. In order to make the detection results more accurate, please ensure that the ambient temperature during use is 5 ℃ -35 ℃ (41 ℉ -95 ℉), the relative humidity of the air is less than 80%, and the gemstone being tested must be clean, dry, and at room temperature.
