A Key Parameter for Improved Energy Efficiency THERMAL CONDUCTIVITY The HFM is an exact, fast and easy-to-use instrument for measuring the low thermal conductivity, λ, of insulation materials. el, S ilico n Alum inum , Gra phit Silve e r, Co ppe r , S Diam ilico n Ca ond rbi * excluding HFM 706 Lambda Large The HFM 706 Lambda series is based on various relevant standards, e.g., ASTM C518, ISO 8301, JIS A1412, DIN EN 12664* and DIN EN 12667. Quality control alongside production to ensure that materials meet the required specifications Development of new materials with optimized thermal properties...

In a heat flow meter (HFM), the test specimen is placed between two heated plates controlled to a user-defined mean sample temperature and temperature gradient to measure heat flowing through the specimen. The specimen thickness, L, is measured by an internal thickness gauge. Alternatively, the user can enter and drive to the desired thickness, which is of particular interest for compressible samples. Thermal Conductivity . λ in SI unit [W/(m·K)] or Q L λ = – –– British Thermal Units A ΔT [Btu in/(h·ft2·°F)] Thermal Resistance Since the Heat Flow Method is a relative method, the instrument must...

Thermal Analysis Made More Sustainable Reduced Energy Consumption and Operating Costs In standby, the HFM 706 Lambda can be switched to the energysaving Eco Mode or to Idle Mode. The timing for when each mode is active can be adjusted via a scheduler. The SmartMode software offers a user-defined time schedule for activating either Idle or Eco Mode. In Eco Mode, the HFM plate temperature control and chiller are deactivated, resulting in a negligible energy consumption level for the entire system. During periods when no measurement runs, e.g., overnight or during the weekend, energy savings in...

HFM 706 Lambda Series DEDICATED TO SMALL-, MEDIUMAND LARGE-SIZED SPECIMENS HFM 706 Lambda Large HFM 706 Lambda Medium HFM 706 Lambda Small Three Instrument Versions – Perfect for Individual Sample Dimensions The HFM 706 Lambda is available in three sizes. Choose from among: Small 203 mm x 203 mm x up to 51 mm Medium 305 mm x 305 mm x up to 105 mm Large 611 mm x 611 mm x up to 200 mm We understand that finding the right fit is important, so we've made it easy to have an instrument that fits your specimen size. Whether you're working with small laboratory samples or larger industrial materials,...

Perfect for Most Sample Types Peltier Temperature Control for Hot and Cold Plates The plate temperatures are individually controlled by bidirectional heating/cooling Peltier systems connected to an external chiller. Thanks to optimized temperature control, the high-output Peltier elements accomplish thermal equilibrium and produce data sets within a short time - a productivity increase for your laboratory. The plates of the HFM 706 Lambda can be separated just slightly at the end of a test. For the next test, the change of specimens can thus be carried out within seconds. This feature minimizes...

Measuring the Thermal Conductivity of Compressible or Oversized Specimens at Variable Density HFM 706 Lambda Large for Oversized, Long Samples The HFM 706 Lambda Large has a second opening opposite the front door of the instrument. This makes it possible to insert specimens of different lengths. Insulation panels can be tested with the excess material extending beyond the front and back of the instrument. This is particularly useful for Vacuum Insulation Panels (VIPs), which are often supplied as long panels rather than square samples, and where cutting to size is not possible. environments,...

ACCESSORIES AND MORE Materials beyond the routine capability of the HFM method can be tested by inserting additional thermocouples and rubber interface pads – eliminating the impact of interface resistance for low thermal resistance and correspondingly higher thermal conductivity materials. Improved Measurement Precision for Rigid Specimens with Low Thermal Resistances The HFM 706 Lambda series can be equipped with an optional Instrumentation Kit* that expands its range to lower thermal resistances (down to 0.02 (m2·K)/W) to allow for tests on materials such as concrete, wood products, brick,...

The instrument is delivered calibrated and a reference specimen is optionally included for verification. Of course, the list of available reference materials can be expanded by the operator. Pre-Calibrated with Certified Reference Materials The HFM system is delivered pre-calibrated with international certified reference standards of known thermal conductivity. This establishes precise correlation between the signal output of the transducers and the actual heat flow. Thermal resistance and thermal conductivity are determined once the user-adjustable stability criteria are met. Of course, customers...
