All testing functions are automatically completed; Motor controlled tablet movement; The measurement setup and operation are very fast; The sample is sandwiched between two heat flow sensors for testing, with a fixed or adjustable temperature gradient.

Product Details

HFM436LambdaNaichi heat flow method thermal conductivity analyzerCapable of measuring samples of 305 × 305mm (or 610 × 610mm), with a thickness range from a few millimeters to 100 (or 200) mm. All testing functions are automatically completed; Motor controlled tablet movement; The measurement setup and operation are very fast; The sample is sandwiched between two heat flow sensors for testing, with a fixed or adjustable temperature gradient. After a few minutes of temperature and temperature gradient stabilization, the thermal conductivity and thermal resistance of the sample are measured using an embedded controller or external computer.

Automatic board movement and sample thickness measurement simplify the testing preparation process.

The flat temperature control system (US-patent No. 5940784 (1999)) and dual heat flux sensor design enable the instrument to quickly provide accurate measurement data.

The measurement of HFM436Lambda thermal conductivity complies with relevant international standards such as ASTMC518, ISO8301, JISA1412, DINEN12939, DINEN13163, and DINEN12667.
