Abstract: This study presents fabrication of an experimental setup based on line heat source method and automate data acquisition software (LabVIEW) was used to measure thermal conductivity (TC) of two-phase materials (TPMs) with various temperatures. TC measurement of various TPMs has been carried with a minimum value (0.178 W/m°C) for saw dust and maximum value (0.64 W/m°C) for iron powder. Reliability tests were conducted on glycerin to validate experimental set-up. Using TC values at different temperatures, thermal diffusivity can also be found out. Thermal probe method of determining TC is one of the best methods available owing to its simplicity and ease of construction and usage.
