High Precision Thermal Conductive Tester , Automatic Test And Print Storage
Summary:
Check the thermal conductivity and thermal resistance by the heat flux method is popular in the world, to achieve automatic detection with computer generated test report. Instruments by adding hot surface temperature stability on the sample side heat transfer to the surface through the specimen, transfer heat flux measurement to calculate the thermal conductivity and thermal resistance. Imported sensors and computer technology, measurement accuracy well, high reliability and good reproducibility. Particularly suitable for measuring low thermal conductivity (accurate to 0.1MW). Can be used for plastic, rubber, insulation materials testing, widely used in universities, research institutes, quality inspection, factories and mines. Reference: GB/T10295-2008 (heat thermal insulation -- Determination of steady-state thermal resistance and related properties the test method and ASTM C518-04 method) to measure the transmission characteristics for steady state heat flux and heat with heat flow meter method.
