Transient line heat source（TLS）Instrument complianceASTM D5334andIEEE 442-2017Standard. The sensor needle is sealed in150mmThe100mmor50mmComposed of fine heating wires and temperature sensors in steel pipes, which can be inserted into the sample to be tested using a constant current source（q）Transfer heat to the sample and record the temperature rise during the defined time period. Thermal conductivity（k）Using the slope in the logarithmic plot of temperature rise and time（a）To calculate, the lower the slope, the higher the thermal conductivity of the sample; The higher the slope, the lower the thermal conductivity of the sample.
