HCDR-P flat plate thermal conductivity meter Introduction: The HCDR-P flat plate thermal conductivity tester is based on the principle of unidirectional stable thermal conductivity. When the upper and lower surfaces of the sample are at different stable temperatures, the thermal flux passing through the effective heat transfer area of the sample and the temperature difference and thickness between the two surfaces of the sample are measured to calculate the thermal conductivity. The core lies in calculating the thermal conductivity by measuring the temperature difference, heat flow rate, and geometric dimensions of the sample on both sides. The flat plate method thermal conductivity meter is a steady-state method thermal conductivity meter designed for building insulation materials, composite materials, multi-layer materials, and porous materials based on the measurement principle of the protective flat plate method. The flat plate method thermal conductivity meter has high measurement accuracy, good temperature control stability, and can automatically apply pressure and measure thickness, meeting the needs of experiments at different temperatures. characteristic: The fully temperature control system adopts an optimized dynamic PID algorithm, which greatly avoids the shortcomings of traditional PID algorithms and improves the stability of temperature control. 2.
