Xiangtan XiangkeDRX-3Hotline Thermal Conductivity Tester, High-Temperature Thermal Conductivity Instrument for Refractory Materials

Xiangtan XiangkeDRX-3Thermal Conductivity Tester

I. Overview

    DRX-3Thermal Conductivity Test Instruments utilize the transient hot wire method, including cross-line and parallel-line techniques, primarily measuring the thermal conductivity, thermal diffusivity (heat transfer coefficient), and specific heat capacity of solid and powdered materials at various temperatures. They feature high precision, high resolution, and high reproducibility. The instruments are computer-controlled for automatic measurements. Widely applicable in research institutions, quality inspection, and industrial departments for material thermal conductivity measurements.

This instrument is a product of our factory.DRX-2Revised development and design on the basis, enhancing measurement accuracy and reproducibility, with a more rational structure and easier usage. Model Classification:DRX-3APrimarily utilizes the cross-hotline method (parallel line method can also be used for measurement)5w/mkThe following materials);DRX-3BUtilizing the parallel line method, measure less than25w/mkMaterials.
