High precision material thermal conductivity coefficient tester (plate heat flow meter method)

 
Outline
Adopt internationally popular heat flow meter thermal conductivity coefficient and thermal resistance detection methods, with computer to realize automatic. Detection, generate test reports. The instrument adds stable thermal surface temperature on one side of the sample, heat goes through the sample to deliver to the cold side to detect transferred heat flow to calculate the thermal conductivity and thermal resistance. It adopts imported sensors and computer technology, good measurement accuracy, high reliability, and good repeatability. Particularly suitable for low thermal conductivity measurement (accuracy to 0.1mw). Can be used in plastics, rubber, insulation materials and other tests, Widely used in Colleges and Universities, Research institutes, factories, quality inspection. Reference Standard: GB / T10295-2008 (Steady state thermal resistance of thermal insulation materials And relevant special
