The MTPS method employs a single-sided, interfacial heat reflectance sensor that applies a momentary constant heat source to the sample. Typically, the measurement pulse is between 1 to 3 seconds. The temperature behavior as a function of time is analyzed with the aid of a calibration to give thermal properties of the sample. Thermal conductivity and effusivity are measured directly, providing a detailed overview of the heat transfer properties of the sample material. Measurement Range 0.01 to 500 W/mK Sample size Min. diameter of 18 mm Min. thickness is dependent on thermal conductivity Temperature range -50 to 200 °C Recommended Material types Solids, liquids, powders and pastes ASTM/ISO/EN Standards ASTM D7984
