Product Introduction<\/h3>\n\n\n\n

Adopting the internationally\u2011popular heat\u2011flow\u2011meter method for thermal conductivity and thermal resistance measurement, this instrument realizes fully\u2011automatic test and generates test reports with computer. A stable hot\u2011side temperature is applied to one side of specimen; heat passes through the specimen to cold side. The transmitted heat flux is measured to calculate thermal conductivity and thermal resistance. Equipped with imported sensors and computer technology, it features favorable measurement accuracy, high reliability and good repeatability. It is especially suitable for measuring low thermal\u2011conductivity values (precision up to 0.1\u202fmW). It can be used for testing plastics, rubber, thermal\u2011insulation materials and so on.<\/p>\n\n\n\n

It is widely applied in universities, scientific research institutes, quality\u2011inspection departments and industrial plants. Reference Standards: GB\/T 10295\u20112008 (Determination of Steady\u2011State Thermal Resistance and Related Properties of Thermal\u2011Insulating Materials \u2014 Heat\u2011Flow\u2011Meter Method), ASTM C518\u201104 Standard Test Method for Steady\u2011State Heat Flux and Thermal\u2011Transmission Properties by Means of the Heat\u2011Flow\u2011Meter Technique.<\/p>\n\n\n\n
