Graphite and Carbon Materials Thermal Conductivity Tester
Published: 3/27/2019
High-temperature tester based on the direct-current longitudinal heat-flow method for measuring thermal conductivity of electrically conductive materials. Suitable for metals and graphite across a wide conductivity range with automated data acquisition and analysis.
Product Description
The DRX-II-JH measures the thermal conductivity of conductive materials at elevated temperatures using a longitudinal heat-flow method in which the specimen is directly energized. The system is designed for metals such as copper and stainless steel, as well as non-metal conductive materials including graphite, enabling research on heat transfer performance.
The measurement approach conforms to GB3651-83 for high-temperature thermal conductivity of metals and GB8722-88 for intermediate-temperature thermal conductivity of graphite materials. Automated control allows computer-driven testing with controllable heating rates, data acquisition, and report output, and the system can be configured with vacuum or protective atmospheres as required.
