Abstract | An instrument for rapid determination of thermal conductivity of liquids and solids is described. From the known relationship between thermal conductivity and snow density, measurements can be calibrated in terms of snow density. With a small, 4-mm-diameter probe of coaxial design and differential temperature measurements, rapid, single value reasings are made in a few seconds. These readings compare favorably with the customary thermal conductivity analysis in which a time-temperature relationship developed over many minutes is normally required. Equipment is small, lightweight. and portable.A calibration of the density probe in liquids and snow (density range of 0.06 to 0.4) is shown. |
