Thermal storage coefficient tester

The thermal storage coefficient tester can detect a wide range of materials without the need for special preparation of test samples. It can simultaneously detect thermal conductivity, thermal conductivity (thermal diffusion coefficient), specific heat capacity, thermal storage coefficient, and thermal resistance.

summary:

　　Thermal storage coefficient testerAdopting the transient plane heat source method, based on TPS transient plane heat source technology, using a Hot Disk probe. The advantages of this instrument are:

1. Directly measuring heat propagation can save a lot of time;

2. Will not be affected by contact thermal resistance like the static method;

3. No special sample preparation is required, only a relatively flat sample surface is needed for solid materials. Different types of materials use different testing schemes and computational mathematical models, which have the advantages of 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.
