Product description HFM 446 Lambda Serie
Saving and Efficient use of Energy
Never before has the topic of the saving and efficient use of energy attracted as much attention in economics and politics around the globe as it does today. Research and development efforts in industry and academia worldwide are addressing topics that contribute to saving energy or generating energy from alternative resources.
There is enormous potential, especially in the areas of insulation materials and the efficient thermal insulation of residential and commercial buildings. It is thus all the more important for insulating materials to be able to be manufactured with a high and steady level of quality and brought onto the market under strict control of their performance characteristics.
There are numerous standards and guidelines to which these products are subject in order to really guarantee these properties for the huge amounts of insulating materials being produced worldwide.
In a heat flow meter (HFM), the sample is placed between two heated plates, which are controlled for a user-defined average sample temperature and temperature drop, to measure the heat flowing through the sample. The heat flow through the sample is measured by two calibrated heat transducers.
The main role is played by the material parameter thermal conductivity. This is the amount of heat per second that flows through a material layer of 1 meter in an area of 1 m² if the temperature difference is 1 K). The thicker the material layer through which the heat flows, the higher the thermal resistance (R-Value) that the material layer presents to the quantity of heat to be transported. The reciprocal value of the thermal resistance is the thermal transmittance (U-Value), usually specified for structural components.
It does not matter what kind of material has to be analyzed. The HFM 446 Lambda can be used for EPS, XPS, PU foam, mineral wool, foam glass, cork, fleece or natural fiber materials, but also when it comes to building materials with phase change, concrete, plaster or polymers. The new standardized method for measuring thermal conductivity is applicable in R&D purposes and in quality assurance.
The Proteus® Software offers everything you need to perform the analysis and evaluate the data. By combining easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly while also enabling advanced analysis
All relevant results can be printed directly by the integrated printer or a report can be generated by the software.
With the “Report” button, reports can be generated quickly and easily using various templates. One of the templates is fully furnished according to the requirements of ASTM C518. Each report can be adapted to the customer's own corporate design. Moreover, data can be easily exported to Word or Excel with just a few mouse clicks. There is also an option to build a full report with graph and results with one click.
Each Proteus version is linked to the specific instrument, but can of course be installed on other/ multiple computer systems.
The HFM 446 series offers three different versions.
