【 摘 要 】

In this study, thermoelectric module is used as a heater for thermal conductivity measurement of solid materials. Principle of temperature gradient is adopted in this measurement. Stainless steel is utilized as a reference material. Each temperatures are measured by t-type thermocouple and the thermal conductivity is then calculated. The result shows that the thermal conductivity of tested materials is 0.303 W/mK with maximum uncertainty of 3.79%. To assure the result of this measurement, the thermal conductivity of tested material is also measured by laser flash method. The difference result of both measurement is below 5%.
