LDR-II Transient Laser Thermal Conductivity Tester Introduction: This instrument is suitable for measuring the thermal diffusivity and thermal conductivity of high thermal conductivity solid materials, such as metals, graphite, etc., according to the national standards GB/T 22588-2008 "Flash method for measuring thermal diffusivity or thermal conductivity" and ASTM E 1461-2001 "Test method for determining thermal diffusivity by flash method". Testing principle: Thin samples are irradiated with high-intensity short-term energy pulses, and 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 time required for the temperature on the back side of the sample to rise to half of its maximum value (also known as the half heating time) is calculated quickly using a specialized mathematical model and a computer to calculate its thermal diffusion coefficient α and thermal conductivity coefficient l. Our company's independently developed LDR-I transient laser thermal conductivity tester has obtained a national patent (certificate number: 13751552), which is suitable for testing high thermal conductivity materials such as metals, graphite, graphene, and silicon carbide. It has the advantages of fast measurement speed and accurate measurement results, and high cost-effectiveness to meet the production, quality inspection, and research and development needs of related industries. Technical parameters: 1. Sample size range: Φ 12 × (0.1-5) mm, 2. Measurement range of thermal conductivity: 0.1-2000 w/m.k 3. Computers can simultaneously calculate multiple thermal parameters such as thermal diffusivity (thermal conductivity) and specific heat capacity 4. Laser source power: 200W adjustable 5. Test accuracy: ± 3% 6. Repeatability: Two measurement deviations<± 3% 7.
