The double plate thermal conductivity tester, with an integrated water bath thermostat and computer-controlled measurements, tests thermal conductivity of homogeneous plates (e.g., plastics, rubber, glass) and granular/bulk/soft materials. It is widely used by heat insulation material producers, quality inspection departments, universities, and research institutes.
