Abstrakt: The construction of an instrument for measurements by the absolute hot-wire method is described. The thermal conductivity of toluene, benzene, carbon tetrachloride, and air in the temperature range 20–160° C was measured to an accuracy of 1% Natural convection in the cylindrical gap (d=0.675 mm) when the measuring cell is vertical occurs when GrPr > 3400.
