1.Description:
This instrument adopts the internationally popular method of using thermal flow meters to measure thermal conductivity and thermal resistance. It is equipped with a computer to achieve fully automatic testing and generate experimental reports. It is redesigned based on the DRPL-I type flat plate thermal flow meter for thermal conductivity testing instrument produced by our company, and is capable of meeting the testing requirements of 400×400×(5-80) insulation bricks.
This instrument is based on the steady-state plate method testing principle. A stable temperature is added to the hot surface, and the heat passes through the sample to the cold surface. The transferred heat flow is measured. Then, the thermal conductivity and thermal resistance can be calculated based on the thickness of the sample and the heat transfer area. This testing method is simple, fast, and has good repeatability. It is very suitable for research and development in material heat transfer. It can be used for testing of rocks and soils, foams, cement, insulation materials, etc., and is widely applied in universities, research institutes, quality inspection, factories and mines.
