I. Scope of Application: Applicable to the thermal conductivity of dry clay and sandy soil specimens. The thermal resistance of the specimen should be greater than 0.1m ².k /W.
The method of detecting the thermal conductivity and thermal resistance of clay, sand and other materials by using a heat flow meter is connected to a computer to achieve fully automatic detection and generate an experimental report. The instrument calculates the thermal conductivity and thermal resistance by applying a stable hot surface temperature to one side of the sample. Heat is transferred from the sample to the cold surface (room temperature), and the transferred heat flow is measured. It is specially equipped with a rock and soil sample cylinder and a specific heat capacity testing device, which can be used for thermal conductivity analysis and specific heat capacity determination of clay, sandy soil and other soils.
Ii. Compliance with Standards
Complies with GB/T10295-2008 "Determination of Steady-state Thermal Resistance and Related Properties of Thermal Insulation Materials - heat flow meter method" and ISO/DIS8301 "Thermal insulation - determination of steady-state thermal resistance and related properties ---- heat flow meter apparatus".
