CEP

The educational purpose of the Effusivimeter allows to measure the thermal conductivity of all insulating materials such as polystyrene, polyurethane, mineral wool, terracotta/raw, ceramics, plastics, wood, the super insulators and many others.

Our device consists of a thermal shock probe, to be placed between two samples of the material to be characterized (symmetrical assembly), an electronic acquisition box, a graphical interface software to manage the tests and process the results and a Practical Work document.

Our device complies with ASTM D5930-97 standards.

The principle of this shock probe is to produce locally a low heating of the material (a few degrees above the sample) and to measure this temperature rise over time (duration of a few minutes).

By mathematical processing of this signal integrated in the supplied software, the identification of the thermal conductivity is achieved.
