DRX-II-300A Thermal Conductivity Machine
مقدمة
It is mainly used to test the thermal conductivity of construction insulation materials, زجاج, fiber, foam and so on. Testing materials include fiber board, loosing filler glass fiber, ceramic fiber (XPS/EPS/PUR, إلخ.), foam plastic, inter-layer composite plate, vacuum plate, rubber products, cement products, concrete brick, powder materials, filler materials, gypsum board and so on. The tester is in line with the latest national standard GB/T 10294-2008 guarded hot plate apparatus, ASTM C518, ASTM C177 and ISO 8302 Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means of the Guarded-Hot-Plate Apparatus. It is in full compliance with the national thermal conductivity measurement standard with its stable and accurate temperature control technology, computer interface, software’s real-time monitoring and control, data processing and saving connecting. With these advantages, it is applied widely in materials properties detection organization, scientific research institution, quality detection department of factory, institutions of higher education teaching and research.
