The thermal conductivity tester developed using Transient Plane Heat Source Technology (TPS) for testing the thermal conductivity of a wide variety of materials. Transient planar heat source method is the latest in the study of thermal conductivity, which brings measurement technology to a whole new level. It can quickly and accurately measure the thermal conductivity when researching materials, which provides great convenience for enterprise quality monitoring, material production and laboratory research. The instrument is easy to operate, the method is simple and easy to understand, and will not cause damage to the sample to be tested.
Suitable for metal, ceramic, alloy, ore, polymer, composite, paper, fabric, foam (surface-level insulation, sheet), mineral wool, cement wall, glass reinforced composite board CRC, cement polystyrene board, sandwich Concrete, FRP panel composite panels, paper honeycomb panels, colloids, liquids, powders, granules and paste solids, etc., have a wide range of test objects.
