Fully Automatic High-Precision Heat Flow Method Thermal Conductivity Meter

The DRH-30S Fully Automatic High-Precision Heat Flow Method Thermal Conductivity Meter uses the heat flow method to measure the thermal conductivity, thermal diffusivity, and thermal fusion of different types of materials. This instrument is based on the ASTM D5470 standard test method for thermal transmission of thermally conductive electrical insulating materials. Reference standards include ASTM C518-04 for steady-state heat flux and thermal transmission characteristics measurement using heat flow meter method; GB10295-2008 for steady-state thermal resistance and related characteristics of insulation materials (heat flow meter method); GB/T25261-2018 appendix A requirements for thermal conductivity measurement of reflective insulation coatings for buildings, and other related international standards. The instrument is capable of fully automatic detection of thermal conductivity and thermal resistance for sponge-type porous materials, plastics, rubber, glass, fibers, polystyrene boards, extruded boards, foamed concrete, hollow glass, ceramics, rocks, geotechnical materials, refractory materials, polymer composites, nylon, resins, and insulation materials. It features automatic pressurization and automatic thickness measurement functions, allowing tests under different pressures while reducing manual measurement errors. Multi-layer technology can be used for accurate measurement of films. According to the principle of GB/T 25261-2018 "Reflective Insulation Coatings for Buildings," the measurement principle is to position the sample between a hot plate and a cold plate to measure heat flow. It can operate independently or under PC control, providing fast and accurate measurement results. It is applied in material performance testing agencies, scientific research institutions, factory quality inspection departments, and higher education teaching and research. Main technical parameters:
