High-precision Material Thermal Conductivity Tester
It adopts the internationally popular method of heat flow meter to detect thermal conductivity and thermal resistance, and realizes fully automatic detection with computer and generates experimental report. The instrument adopts to add stable hot surface temperature on one side of the specimen, the heat is transferred to the cold surface through the specimen, and the transferred heat flow is measured to calculate the thermal conductivity and thermal resistance. Adopting imported sensors and computer technology, the instrument is characterized by good measurement accuracy, high reliability and good repeatabilitygood characteristics. Especially suitable for low thermal conductivity measurement (accurate to 0.1mw). It can be used for testing plastics, rubber, thermal insulation materials, aerogel panels, vacuum glass, etc. It is widely used in colleges and universities, scientific research institutes, quality inspection, factories and mines.
