ASTM E 1461 LDR-II Transient Laser Thermal Conductivity Tester Thermal Diffusivity Testing Machine
1.use
This instrument is suitable for measuring the thermal diffusivity and thermal conductivity of high thermal conductivity solid materials, such as metal, graphite, according to the national standard GB/T 22588-2008 "flash method of measuring thermal diffusivity or thermal conductivity", ASTM E 1461--2001 "flash method of measuring thermal diffusivity test method". Test principle: the thin sample is irradiated by high-intensity short-time energy pulse, the front of the sample absorbs pulse energy to increase the temperature of the back, and the temperature change of the back is recorded. The time required for the temperature of the back of the sample to rise to half of the maximum value after receiving light pulse irradiation (also called half-heating time) is used to quickly calculate the thermal diffusivity α and thermal conductivity l by using a computer through a special mathematical model.
The LDR-11 transient laser thermal conductivity measuring instrument independently developed by our company has obtained the national patent (Certificate number: 13751552), which is suitable for the test of metal, graphite, graphene, silicon carbide and other high thermal conductivity materials. It has the advantages of fast measurement speed and accurate measurement results, and its high cost performance meets the needs of production, quality inspection and research and development in related industries
