Product Description

Geotechnical (stone) thermal conductivity instrument Heat flow meter ASTM C518
1.Product introduction
The thermal conductivity and thermal resistance of soil such as clay, rock, sand, aerogel plate and vacuum glass were detected by heat flow meter, and the automatic detection was realized by computer, and the experimental report was generated. The instrument adopts a stable hot surface temperature added to the sample side, the heat is transferred to the cold surface (room temperature) through the sample, and the heat transfer is measured to calculate the thermal conductivity and thermal resistance. Specially equipped with rock and soil sample tube and specific heat capacity test device, it can do heat conduction analysis and specific heat capacity measurement of clay, rock and soil, sand and other soils. Instrument reference standard: GB/T10295-2008 (Determination of steady-state thermal resistance and related properties of thermal insulation material heat flow meter method) and ASTM C518-04 test method for determination of steady-state heat flux and heat transfer characteristics by heat flow meter method.
