It is mainly used to test the thermal conductivity of building materials, glass, fiber, foam and so on. Testing materials include fiber board, loosing filler glass fiber, ceramic fiber (XPS/EPS/PUR, etc.), foam plastic, inter-layer composite plate, vacuum plate, rubber products, cement(concrete) products, powder materials, filler materials, gypsum board and so on. The tester is in line with the latest International standard ASTM C177 and Indian standard IS: 3346-1996. It is in full compliance with the national thermal conductivity measurement standard with its stable and accurate temperature control technology, computer interface, softwares 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.
