Scientific, Laboratory Equipment & Service


The LINSEIS Heat Flow Meter provides a rapid and easy to use instrument to determine the thermal conductivity properties of low thermal conductivity insulation materials as well as all other materials with a high level of accuracy. The instrument is designed per ASTM C518, JIS A1412, ISO 8301 and DIN 12667. The principle of measurement is to position a sample between a hot and a cold plate and to measure the heat flow. 

System Design

The LINSEIS Heat Flow Meter is a robust and reliable instrument. Its unique design enables highly accurate measurements within minutes. The system provides an excellent long term stability enabling precise long term aging studies. Fast measurement cycles as little as 15 minutes can be achieved, resulting in a high sampling rate. To enable these fast and precise sampling intervals the instrument uses a dual sensor arrangement. An integrated length measurement provides immediate sample thickness data.

Instrument features:

  • Highest precision and accuracy
  • Very robust design
  • Very easy handling
  • Fast sampling (approx. 15min for QC)
  • Automated operation
  • No cooling water required
  • No PC required
