Multi-function Fast Thermal Conductivity Tester (Transient Plane Heat Source Method, Hotdisk Method), TCM-DRE-III, This series of Thermal conductivity instrument uses transient plane heat source method, the instrument based on TPS transient plane heat source technology, with Hot Disk as the probe thermal conductivity tester. The hot Disk method has the following advantages:(1) direct measurement of heat transfer, you can save a lot of time;(2) will not be the same as the static method by the impact of thermal resistance;(3) No special sample preparation is required, for the solid material, only need the relatively flat surface of the sample. It has the advantages of fast measurement speed, wide application range, and the ability to successfully avoid the influence of natural convection during the experiment. It is the popular test method. Equipment reference standard: ISO 22007-2 2008Composite materials: glass composite CRC, cement enhanced polyphony board, sandwich concrete, fiberglass panel composite plate, paper cellular plate
