summary

This instrument is on the basis of stabilizing the heat conduction principle one-wayly, when on the sample, go to the two sides at different steady temperature, measure the difference in temperature and thickness between two surfaces of thermal current and sample of the area of conducting heat effectively through the sample, calculate the coefficient of heat conduction. Measure the research department and test the requirement about the high precision of the material heat conduction coefficient after meeting materials. The instrument consults the standard: GB/T3392-82 " coefficient test method of the plastic heat conduction, protect dull and stereotyped law of heat ", GB/T3139-2005 " fibrous reinforced plastics heat conduction coefficient test method " " glass fibre reinforced plastic heat conduction coefficient test method ", GB/10294 " adiabatic material steady state thermal resistance and relevant determination of characteristic protect the hot board law ",etc.. Mainly test materials such as plastics, glass, fiber, foam,etc.. Apply to large and medium universities and colleges extensively, R&D institution, quality testing department and material for producing factory analyze that measures.
