TCT-2L Transient Laser Thermal Conductivity Testing Machine Flash Method

TCT-2L Transient Laser Thermal Conductivity Tester (Flash Method) 

Description

TCT-2L Transient Laser Thermal Conductivity Tester is suitable for measuring the thermal diffusion coefficient and thermal conductivity of solid materials with high thermal conductivity, such as metal, graphite, etc., according to the national standard GB/T 22588-2008 "Measurement of thermal diffusion coefficient or thermal conductivity by flash method", ASTM E 1461--2001 " Test Method for Determination of Thermal Diffusion Coefficient by Flash Method". Testing principle: A 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 on the back side. The temperature change on the back side is recorded. After receiving the light pulse irradiation, the temperature on the back side of the sample rises to half of the maximum value. time (also called half-heating time), and use a computer to quickly calculate its thermal diffusion coefficient α and thermal conductivity l through a special mathematical model.

The TCT-2L transient laser method thermal conductivity tester independently developed by our company has obtained a national patent (certificate number: 13751552). It is suitable for testing high thermal conductivity materials such as metal, graphite, graphene, silicon carbide, etc., and has fast measurement speed. , accurate measurement results and other advantages, and high cost performance to meet the needs of production, quality inspection, and research and development in related industries.
