The heat flow meter (HFM) method is mainly used to test thermal conductivity and thermal resistance of insulation samples. It is not an absolute method, therefore, the heat flow meter output needs to be calibrated with a standard material. NETZSCH-Gerätebau GmbH has recently qualified its own factory standard for calibration and validation of heat flow … Read moreNETZSCH EPS – A New and Affordable Standard Material for Testing Thermal Conductivity with HFM Instruments
Humidity plays a major role in the quality assurance of insulating materials. Ignorance in dealing with condensation and establishing good measurement conditions can result in unexpected measurement results. This article shows methods, that helps to overcome condensation issues in the quality assurance of thermal insulation materials.
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?
The third-party control of the declared product performance increases the level of security of the proof of usability of insulating materials for the relevant national applications.
Digitization is the biggest change in the way we do business today. Enterprises that successfully adjust to this change can improve productivity
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.
NETZSCH is nominated for the Global Insulation Awards 2018 in the following categories:
Global Insulation Supplier of the Year (technology/equipment)
Global Insulation Technical Innovation Award with our Heat-Flow-Meter HFM 446 Lambda Series

There are many applications for a Heat Flow Meters – but is it the right measurment method for thermal conductivity for my material or product?
This article shows how the thermal conductivity of vacuum insulation panels can be determined – traceable to international thermal conductivity standards!
Saving energy – this applies in the course of the Paris Agreement on Climate Change at international level. Awareness of the reduction of CO2 emissions is growing. Most countries have set themselves ambitious goals. In other words: a good sign for a positive development of the insulation market.
