• Description：this instrument uses internationally the popular heat flow meter examination thermal conductivity and the thermal resistance method, matches the computer to realize the completely automatic examination, the production test report. Uses simulates the aluminum alloy molding actual service condition to carry on the test, faces in the molding joins the stable fire surface temperature openly, the quantity of heat transmits (room temperature) grimly through the molding, the survey transmission"s heat flow may calculate the thermal conductivity and the thermal resistance. The molding environment uses the natural air environment, with the aluminum alloy molding actual use environment match case, the thermal conductivity which and the thermal resistance data obtains not can only judge the aluminum alloy molding accurately the heat-transfer property, moreover provides the powerful data support for the reality engineering design computation. this test method is simple, quick, the duplication is good. Is suitable for the molding heat transfer aspect research and the development. May also use in tests and so on plastic, rubber, graphite, thermal insulation material, widespread application in universities, colleges and institutes, scientific research courtyard, quality testing, factories and mines. this instrument reference standard: ASTM C518-04 uses the heat flow meter law determination stable state heat flux and the heat transfer characteristic testing method.
