The TPS-50AS thermal conductivity tester can be used to measure the thermal conductivity of different materials, including block solids, metals, liquids, powders, colloids, pastes, films, and insulation materials. Compared to TPS-300E, it features better performance for low thermal conductivity products and significantly improves the measurement accuracy.
1. Integrated model design, more lightweight and convenient.
2. Fully automated setting of benchmarks and power greatly improves the efficiency of experiments.
3. Fully upgraded instrument software, making the operation more user-friendly and increasing the calculation of specific heat capacity.
4. More powerful data analysis, allowing for direct calculation of thermal conductivity and thermal conductivity.
5. A bidirectional operating system that allows software and instruments to be controlled in both directions, making operation more convenient.
6. Wider measurement range thus can meet the testing needs of more types materials.
Testing principle
The transient planar heat source method is based on the principle of one-dimensional unsteady thermal conduction in a plane: a planar heat source in an infinite medium generates a dynamic temperature field inside the medium after receiving an instantaneous heating pulse in the initial thermal equilibrium state. Using the temperature data generated by the thermal conduction process, a function curve is fitted to calculate the thermal conductivity and thermal diffusion coefficient of the sample.
