HEAT FLOW METERS

Features

  • Measurement range: 1/3 – 800 mW/m*K.
  • Automatic sample thickness measurement.
  • Open design, which allows testing whole slabs without cutting off samples (sample’s width and length are unlimited).
  • Steady State Heat flow meters with a constant temperature on both sides of the specimen: temperature fluctuation less than ±0.01 °C
  • Heat flow measured with two separate heat flow sensors.
  • Precise and fast work with excellent reproducibility.
  • Perfect for production and quality control of low thermal conductivity materials.
  • User-friendly, operation requires very little training.
  • Supplied with NIST 1450e or ERM-FC440a Certified Reference Material for the system calibration.
  • NI LabVIEW based software for measurement records, data analysis and storage, clear layout.

Custom-made solutions

Our heat flow meters can be adjusted to the customer’s individual needs or requirements. Typical custom-made solutions include:

  • Broader temperature range
  • Broader measurement range
  • Broader contact pressure range ( e.g. 0 – 20 kPa instead of standard 1 kPa)
  • Regulation of contact pressure.
  • Additional software that enables testing thermal conductivity of samples made of soft materials at various thicknesses
  • Testing smaller samples for R&D purposes, e.g. 80 x 80 mm, 250 x 250 mm.

Custom-made solutions – LM.PLUS 305 VIP

Testing thermal conductivity of large samples of max. 3 m width and unlimited length.

The system can consist of one, two (as in the picture) or more measurement points. The frame size can be adjusted to individual customer needs.

The heat flow meter is open on all its sides, thus enabling measurements at the very center of a sample. This is especially suitable when testing oversized vacuum insulation panels. Such samples are more problematic to test using standard heat flow meters (whose one side is closed), because the measurement area is further from the center of the panel and more to its edge.
