NETZSCH-Gerätebau GmbH Accurate Thermal Conductivity Testing of Insulation Materials - HFM 436 Lambda

With the Heat Flow Meter, HFM 436 Lambda, samples measuring 35 cm x 35 cm or 61 cm x 61 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 computer or external computer determines the thermal conductivity and thermal resistance of the sample. Automatic plate movement and determination of the sample thickness facilitate test preparation. The patented plate temperature control system (US-patent No. 5,940,784 (1999)) and dual heat flux sensors quickly provide accurate data. All test parameters as well as the calibration data are stored in the computer and documented. Enhanced Capabilities Integrated printer Variable external load Extendable to higher conductiv¬ity materials with the optional instrumentation kit Determination of thermal conductivity with the Heat Flow Meter, HFM 436 Lambda, meets the industry standards ASTM C518, ISO 8301, JIS A 1412, DIN EN 12939, DIN EN 13163 and DIN EN 12667.
