TCM-HW-II Transient Fast Hot Wire Method Thermal Conductivity Tester
Brief description
Quickly measure the thermal conductivity of plastics, soil, soft rock, liquids, pastes, granules, powders and other materials using the hot-wire method. Sample shape: block, flake, paste, powder, granule, colloid, or liquid (round, square, or irregular shapes are acceptable, no restrictions on shape), as long as there is a relatively flat sample surface.
Overview
The hot-wire method thermal conductivity meter (transient method) is measured using the line source testing method of a thermal probe. This thermal probe has a very large aspect ratio to achieve the simulation conditions of an infinitely long and infinitely thin heat source. Easy to use, plug-and-play probe sensor quick interface method and simple software interface operation enable users to quickly master and operate accurately. From starting to prepare for the test to getting the results, it usually only takes 1 to 2 minutes. It has the advantages of wide application range, fast measurement speed, and accurate measurement results. It is compact, easy to carry, and more cost-effective to meet the needs of production, quality inspection, and research and development in related industries.
