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.

HFM 436 Lambda - Heat flow meter

With the Heat Flow Meter, HFM 436 Lambda, the thermal conductivity of large-sized, plate-formed insulators is investigated at a fixed or adjustable temperature gradient. The built-in computer – or an externally connected one – delivers the precise measurement data after a short compensation time.
