Our philosophy, to offer you a specific metrology for your needs and based on research. NeoTIM, your thermal measurement solutions.


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.
