HFM 436 Lambda – Heat flow meter Netzsch (Germany)

With the Heat Flow Meter, HFM 436 Lambda, the thermal conductivity of large-sized, plate-formed insulators is investigated at a fixed or adjustable temperature gradient. The built-in computer – or an externally connected one – delivers the precise measurement data after a short compensation time.

תיאור

With the Heat Flow Meter, HFM 436 Lambda, samples measuring 30.5 cm x 30.5 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 conductivity materials with the optional instrumentation kit
