Introduction: This instrument is suitable for measuring the thermal diffusivity and thermal conductivity of solid materials with high thermal conductivity, such as metals, graphite, etc. According to the national standard GB/T 22588-2008 "Measurement of thermal diffusivity or thermal conductivity by flash method", ASTM E 1461--2001 " "Test Method for Determination of Thermal Diffusivity by Flash Method". Test principle: The thin sample is irradiated by a high-intensity short-time energy pulse, the front side of the sample absorbs the pulse energy to increase the temperature of the back side, and the temperature change of the back side is recorded. The time (also called the half heating time), the thermal diffusivity α and the thermal conductivity l are quickly calculated by a computer through a special mathematical model. The LDR-I transient laser thermal conductivity tester independently developed by our company is suitable for the testing of materials with high thermal conductivity such as metal, graphite, graphene, silicon carbide, etc. It has the advantages of fast measurement speed and accurate measurement results. Cost-effective to meet the production, quality inspection, research and development needs of related industries. Technical parameter: 1. Sample size range: Φ12×(0.1-5)mm 2.
