Webb29 dec. 2014 · The thermal conductivity is calculated based on the temperature difference between initial temperature and final temperature after applying heat. The measurement range is 0.3 to 2.0 W m −1 K −1 for thermal conductivity and −10 to 50°C for temperature, respectively. The measurement was done with three different positions on sample surface.
