DRLThermal conductivity meter using heat flow methodaccording toASTM D5470-2017The standard requires design and manufacturing. Our company has accumulated 20 years of experience in production, manufacturing, and user practice, which has continuously improved and matured the performance of this product.Adopting servo motor control for precise automatic pressurization and automatic thickness measurement deviceAnd connected to a computer to achieve fully automatic control. The instrument adopts6Point temperature gradient detection improves testing accuracy. A protective thermal device has been added around the test rod inside the test head (to provide thermal protection for the sample), reducing the impact of ambient temperature on the test. It can test the thermal resistance curve under different pressures and temperatures, and use optimized mathematical models to measure multiple parameters such as material thermal conductivity, thermal resistance, and interface contact thermal resistance.Adopting new technology for automatic compensation of cold end temperature,No longer need to add ice water compensation device.
Users can choose standard and small-sized models (with the same performance) according to their actual land occupation, saving laboratory space.
Widely used in material thermal conductivity analysis and testing in universities, research institutions, quality inspection departments, and production plants.
