Accurate thermal conductivity testing of insulation materials

With the HFM 436 Lambda, samples measuring 30 cm x 30 cm or 60 cm x 60 cm and of variable thicknesses ranging from a few millimeters to 10 (20) cm are tested between two heat flux sensors in fixed or adjustable temperature gradients. After a few minutes for the system to reach equilibrium, the built-in PC or external computer determines the thermal conductivity and thermal resistance of the sample.  
  
Automatic plate movement and determination of the sample thickness simplify test preparation.  
  
All test parameters as well as the calibration data are stored in the PC and documented.  
  
Determination of thermal conductivity with the HFM 436 Lambda meets the industry standards ASTM C 518, ISO 8301, JIS A 1412, DIN EN 12939, DIN EN 13163 and DIN EN 12667.

Features of HFM 436 Lambda

Low maintenance costs The Lambda’s state-of-theart cooling technology works with a Peltier cooling system and requires no external chillers (except for the HFM 436/6 and /1E models) and no CFC or water supply, thereby improving reliability and avoiding maintenance cost and time. The patented plate temperature control system and dual heat flux sensors quickly provide accurate data.   

Excellent stability The instrument is stable within 0.10 - 0.25% over the course of several days, providing excellent repeatability. This allows the use of quick tests as a reliable indicator of product variability.during a production   run. Over extended periods of time, this is valuable for conducting aging studies or examining the long-term consistency of a product.  

Short testing times Steady-state stability criteria can often be met in approx. 15 minutes, resulting in greater laboratory throughput and productivity gains. Due to the dual heat flux transducer arrangement, k-factors are consistently within 0.5% of the fullystabilized value in less than 20 minutes, and for many samples, repeatability of 15-minute tests is typically within a few tenths of a percent.  

Thickness determination The HFM 436 LambdaTM comes with an integrated µm-resolution LVDT system, allowing automatic determination of the samples’ actual thickness within a few seconds.
