TCT-3E multifunctional fast thermal conductivity tester

Shuoboda TCT-III multifunctional fast thermal conductivity tester mainly measures the thermal conductivity, thermal conductivity (thermal diffusion coefficient), specific heat, heat storage coefficient and thermal resistance of solids, rock and soil, powders, liquids, pastes, coatings, films, anisotropic materials, etc.

Description

This instrument adopts the transient plane heat source method, based on the TPS transient plane heat source technology, and uses the Hot Disk probe. The advantages of this instrument are:

(1) Direct measurement of heat transfer can save a lot of time;

(2) It 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 required for solid materials. Different types of materials adopt different test schemes and computational mathematical models, which have the advantages of fast measurement speed, wide application range, and the ability to successfully avoid the influence of natural convection during the experiment. The actual test material range is wide, the thermal conductivity range is wide, the sample processing is simple, and the test speed is fast, which is a relatively popular test method at present.
