This is a high-temperature thermal conductivity test instrument for thermal insulation materials developed on the basis of the DRS-2 water flow flat plate method thermal conductivity tester. Compared with DRS-2, it has improved resolution and automation, shortened test time, easier maintenance, and more reliable instrument performance. This instrument is suitable for testing the thermal conductivity of refractory insulation materials, ceramic fibers, insulation felts, textiles, boards, bricks and other materials at different temperatures. It is widely used in the analysis and testing of materials in universities, research institutes, quality inspection departments and production plants.
