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



Neotim is now marketing a device for characterizing the thermal conductivity of CTMF bâptisé insulating materials


The CTMF measures the thermal conductivity of all insulating materials such as polystyrene, polyurethane, mineral wool, terracotta/raw, ceramics, plastics, wood, supers insulation and many more.

Our device complies with ASTM C518, ISO 8301and EN 12667.

The principle of CTMF is based on the fluxmetric method of producing a temperature gradient according to the thickness of the sample to be characterized and measuring the heat flow through it.

The temperature difference between the two sides of the sample is applied using thermo-elements that are specifically sized.

The thermal flux is measured by thermobatteries according to the mentioned standards. The set is sized to accommodate 150 x 150 mm and a few millimetres to a few centimetres thick test pieces.
