Thermal insulation

Nanoporous Insulation — Thermal Conductivity

How does a measurement in a heat flow meter compare to measurements with other standardized techniques such as guarded hot plate (GHP).

As part of a Round Robin Test, a nanoporous insulation board was measured with different NETZSCH heat flow meters as well as with a guarded hot plate system (absolute measurement technique). The results obtained by the different instruments are in agreement within 2.5% in the overlapping temperature range. This clearly demonstrates the outstanding performance of the HFM 436 Series instruments.
