HFM 446 Lambda Series 
Heat Flow Meter for Testing Insulation Materials Based on ASTM C518, ISO 8301, JIS A1412, DIN EN 12664, and DIN EN 12667 Method and Technique for the Characterization of Insulation Materials.

THERMAL CONDUCTIVITY

• What is the heating/cooling load of a building?
• How does this change with the weather and how can you improve it?
• How can you optimize the heat transfer from an electronic component?
• How do you design a heat exchanger system to achieve the required efficiency and what are the best materials to use?

To answer questions like these, material properties such as thermal diffusivity and thermal conductivity must be known. NETZSCH offers various thermal conductivity testing instruments covering nearly all possible applications and temperature ranges. For the analysis of lower-conductivity materials such as fiber insulations or vacuum insulation panels, NETZSCH stands out with various types of heat flow meters (HFM) for diverse sample dimensions and temperature ranges. The HFM 446 Lambda Series is based on various relevant standards, e.g., ASTM C518, ISO 8301, JIS A1412, DIN EN 12664* and DIN EN 12667.
