LEAT-4 Thermal Conductivity Measurement Apparatus

Thermal Conductivity Measurement Apparatus  There are two method to measure thermal conductivity- steady-state method and dynamic method, this instrument is steady-state method type. In the steady-state method, we heat the sample first, and the temperature difference inside the sample makes the heat transfer from high temperature to low temperature, and the temperature of each point inside the sample will change with the heating speed and heat transfer speed; when the experimental conditions and parameters are properly controlled to make the heating and heat transfer process reach the equilibrium state, a stable temperature distribution can be formed inside the sample The thermal conductivity can be calculated from the temperature distribution. Main technical features:1. It adopts isolated low-voltage heating, which is safe and convenient to use;2. Using national standard thermocouple to measure temperature and Teflon flexible protection tube, the thermocouple is not easy to break;3. T
