DRX-II-300A Intelligent Flat Thermal Conductivity Tester for Insulation Materials

This instrument is mainly used to test the thermal conductivity of solid materials such as building engineering thermal insulation materials, thermal insulation materials, glass, fiber, foam, etc. Test materials include fiberboard, loosely filled glass fiber, ceramic fiber, (XPS/EPS/PUR, etc.) foam plastic, interlayer composite board, vacuum board, rubber products, cement products, powder materials, filling materials, gypsum board, etc. Compliant with the latest national standard GB/T 10294-2008 Protection Hot Plate Method, ASTM C 518, ISO 8302 and other testing standards, it has made significant improvements and upgrades to the original DRX-I-PC dual panel instrument technology, with triple temperature protection to reduce environmental thermal interference. The test piece can achieve automatic parallel adjustment with the hot and cold plates, and the non parallel error on both sides of the test piece is very small. The cold surface has electronic refrigeration technology and other refrigerants such as water medium for users to choose from. The precise and stable temperature control technology computer interface, software real-time measurement and control, data processing and storage and other advanced technologies fully meet the requirements of the national standard for thermal conductivity measurement. Applied to material performance testing institutions, scientific research institutions (institutes), factory quality testing departments, and teaching and research in higher education institutions.
