The HFM-100 Heat Flow Meter (HFM) is engineered as a rapid and user-friendly technique for thermal conductivity and thermal resistance measurement. The system is best suited for insulation products, construction materials, packaging and assemblies. A measurement of thermal conductivity is an indicator of the ability of a material to conduct heat and can be critical for defining energy efficiency and thermal performance in materials. The HFM has been designed to combine the highest accuracy, repeatability, widest temperature range and industry-leading performance all at an exceptional value.
