A thermal flow meter is used to detect the thermal conductivity and thermal resistance of clay, sand and other soils, and the computer is used to realize automatic detection and generate an experimental report. The instrument adopts a stable hot surface temperature on the side of the sample, heat is transferred to the cold surface (room temperature) through the sample, and the transferred heat flow is measured to calculate the thermal conductivity and thermal resistance. Specially equipped with geotechnical sample cylinder and specific heat capacity testing device, which can be used for thermal conductivity analysis and specific heat capacity determination of clay, sand and other soils. Instrument reference standard: GB / T10295-2008 (Determination of steady-state thermal resistance and related characteristics of thermal insulation materials by heat flow meter method) and test method for measuring steady-state heat flux and heat transfer characteristics by heat flow meter method.
