Product Description: | The thermal conductivity and thermal resistance of clay and sand
are detected by a heat flow meter, and the automatic detection is realized by connecting to the computer to generate an experimental report. The thermal conductivity and thermal resistance are calculated by adding a stable hot surface temperature to one side of the specimen, transferring heat through the specimen to the cold surface (room temperature), and measuring the heat flow transferred. It is specially equipped with geotechnical sample barrel 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. |
Scope of application: | Applicable to: thermal conductivity of dry specimens of clay and
sand, and the thermal resistance of the specimen should be greater than 0.1m2.K/W. |
Meet the standards: | It conforms to GB/T10295-2008 "Determination of Steady-state
Thermal Resistance and Related Characteristics of Thermal
Insulation Materials" and ISO/DIS8301 "Determination of Steady-State Thermal Resistance and Related Characteristics ---- Heat Flow Meter Device". |
The main technical parameters: | 1. Thermal conductivity range: 0.015-400W/mk, accuracy better than
5%. (Equipped with a round specimen tube for geotechnical measurement, Ф90mm) 2. Hot surface temperature: room temperature -99.99 °C, temperature measurement by high-degree digital display, 0.2 grade accuracy, resolution 0.01 °C. 3. Cold surface temperature: room temperature, using a high-degree digital display to measure the temperature, 0.2 grade accuracy, resolution 0.01 °C. 4. Hot surface temperature control: room temperature -99.99 °C, temperature measurement by high-degree program-controlled digital display, 0.2 level accuracy, resolution 0.01 °C, plate heater, two-way thyristor control. 5. The cold noodles are forced air cooling. 6. Adopt computer automatic test. 7. WPY heat flux meter is adopted, and the heat flux parameter is 23.26w/m2.mV. 8. Plexiglass windshield is used to directly observe the experimental process. 9. Heat transfer area of hot and cold plates: 150×150 (mm). 10. Adjustable spacing between hot and cold plates: 0-160 (mm). |
