DRX-3B Thermal Conductivity Tester (parallel hot wire method)

The DRX-3 thermal conductivity tester adopts the transient hot wire method and parallel line method, mainly measuring the thermal conductivity, thermal conductivity (thermal diffusion coefficient), and specific heat capacity of solid and powder materials at different temperatures. Featuring high precision, high resolution, and high reproducibility. Automatically measured by computer control. Widely applicable for measuring the thermal conductivity of materials in research institutions, quality inspection, factories and mines, and other departments.

Standard:

GB/T 5990-2006 "Test method for thermal conductivity of shaped insulating refractory products (hot wire method)";

GB/T 17106-1997 "Test method for thermal conductivity of refractory materials (parallel line method)";
