Introduction
     The instrument uses the Hot Disk method, based on TPS technology, using a Hot Disk probe。advantage：
       1.Directly measuring heat propagation can save a lot of time；
     2.Will not be affected by contact thermal resistance like static method；
     3.No special sample preparation is required, only a relatively flat sample surface is required for solid materials. Different types of materials adopt different testing schemes and computational mathematical models, which have advantages such as fast measurement speed, wide applicability, and the ability to successfully avoid the influence of natural convection during the experimental process. The advantages of wide range of actual testing materials, wide range of thermal conductivity, simple sample processing, and fast testing speed are currently popular testing methods.
