HFM—HEAT FLOW METER Thermal Conductivity Analyzer

An insulating material is a material with low thermal conductivity, which in the construction industry, equip- ment manufacturing, or the production of refrigerators, freezers, etc. is used for thermal insulation. The physical properties to determine the effectiveness of insulation material are the thermal conductivity, the heat transfer coefficient. The performance of an insolation material component is given by its heat transfer coefficent DELTA . This value can be determined with a HFM where a square between a hot and a cold plate (temperature gradient). The heat transfer coeaffcient can...
