We measured thermal conductivity of Tottori dune sand and water using four methods, single heat probe (SPM), twin heat probe (TPM), dual heat probe (DPM), and Decagon probe (KDM). The measured values were compared. The thermal conductivity values measured with SPM and DPM are similar, and those with TPM and KDM are also similar. The thermal conductivity of water measured with KDM was as high as the value reported in literature, on the other hand the values obtained using SPM and DPM were higher than the reported data. As a result, KDM and TPM are recommended to measure soil thermal conductivity.
