High-Temperature Thermal Conductivity Tester for Carbon Felt
Published: 4/1/2025
High-temperature thermal conductivity tester designed for low-conductivity materials such as carbon felt, refractory carbon materials, ceramic fiber products, composites, and insulation bricks/boards. It uses the heat flow meter method and supports automated testing aligned with GB/T 10295 and related standards for high-accuracy measurements in R&D and quality control.
Product Description
The DRX-II-SPB is engineered to measure the thermal conductivity of low thermal conductivity materials under elevated temperatures, with particular suitability for carbon felt and refractory-related products. Based on the heat flow meter method, the system integrates improved compliance with GB/T 10295 and references GB/T 17911.8-2002 for refractory ceramic fiber products and YB/T 4130-2005 for refractory materials.
The instrument automates data acquisition, state point display, and analysis via dedicated software, while also allowing manual operation when required. Its furnace supports inert or nitrogen atmospheres and vacuum operation, employs molybdenum rod heating up to 1600°C, and incorporates an imported heat flux sensor at the cold side to ensure accuracy and repeatability for laboratory material testing.
A complete system typically includes the tester mainframe, a control cabinet with data acquisition, a recirculating chiller/constant-temperature bath, the analysis software, and a high-temperature heat flux sensor assembly. Users can connect an upper computer for fully automated analysis; a desktop computer can be user-supplied or procured on request.
Site preparation requires standard AC power, water supply for cooling, and adequate space with controlled humidity. The system is suitable for university labs, materials research institutes, and advanced manufacturing quality laboratories dealing with refractory and carbon-based insulation materials.
