Vacuum Insulation Panels or VIPs have a very low thermal conductivity. But how can we determine the thermal conductivity precisely with the lowest possible measurement uncertainty?
For the absolute measurement of thermal conductivity on low-conductive materials the so called “GUARDED HOT PLATE-Method” (GHP) is used. The method is based on a steady-state heat-flow maintained through a material.
Even if those instruments are very complex, NETZSCH found a way to provide the simplest way of absolute thermal conductivity measurements to the industry. The newest SMART MODE Software for GHP’s is a milestone for simplicity to this method.
