NETZSCH EPS – A New and Affordable Standard Material for Testing Thermal Conductivity with HFM Instruments

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

Lambda-Measurement and the Fight against Condensing Humidity

Insulating Materials

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.

How to measure the Thermal Resistance and Thermal Conductivity of Heat Transfer Materials (TIMs) with LFA

Heat must be dissipated from electronic devices quickly and efficiently to ensure optimal performance and to prevent premature component failure. Like CPUs and GPUs, LED inverters as well as photovoltaic inverters require excellent thermal management. Thermal interface materials (TIMs) are available as greases, tapes, filled elastomer pads and phase-change materials.

How to Test the Efficiency and Purity of Silicon Wafers

Silicon-based technologies have always played a significant role within the energy industry. They currently dominate the solar energy market with a market share of over 90 percent.
In addition, the continual improvements being made to silicon (e.g., through silicon crystal growth techniques and enhancements to purity, efficiency, etc.) are securing its strong position within the energy industry over the near future.

Absolute thermal conductivity measurement: Simpler than ever

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.
