Improving speed and precision of using guarded heat flow technique to measure thin specimens

This paper introduces a compensation algorithm and a different-layers calibration method that will improve the temperature measurement speed and thermal resistance elimination of a guarded heat flow meter instrument. Without these additions to the method, heat will travel through a thin slice of material too fast for thermal couples to measure accurately. Thermal contact resistance would cause inaccuracy with a thin slice ...
