Two Gases Tortuosity Meter


Material properties

➡ Characteristic lengths


The Two Gas option includes measurement in air and helium.

  • The combination of the measurements makes it possible to compute the viscous characteristic length as well as the thermal characteristic length;
  • Advanced measurement, signal processing and post-processing for better accuracy.


The system includes two air-coupled ultrasound transducers, one high voltage pulser/receiver system, specimen holders, USB-DAQ and the TOR-X software. The TOR-X software assists the experimenter during the measurement and calculates the statistics on the measurement of viscous and thermal characteristic lengths.
