Measurement of THERMAL CONDUCTIVITY using the HEAT FLOW METER method
Compliant with standards:
- ASTM C518
- ISO 8301
- EN 12667
The CTMF enables the measurement of thermal conductivity of all insulating materials such as polystyrenes, polyurethanes, mineral wools, fired/unfired clay, ceramics, plastics, woods, super insulators and many others.
Principle
The CTMF principle is based on the heat flow meter method, which consists of producing a temperature gradient across the thickness of the specimen to be characterized and measuring the heat flux passing through it.
The temperature difference between the two faces of the specimen is applied using specifically dimensioned thermal elements.
The heat flux is measured by thermopiles according to the cited standards. The assembly is designed to accommodate specimens of 150 x 150 mm and from a few millimeters to a few centimeters in thickness.
