Permeability Tester - Torrent

The Torrent permeability tester permits a rapid and non destructive measurement of the quality of the cover concrete with respect to its durability. Concrete permeability is an excellent indicator of the potential durability and resistance of a particular concrete against the ingress of aggressive media in the gaseous or liquid state. A measurement with Proceq’s permeability tester takes 2-12 minutes.


  • The data is automatically collected by the Torrent permeability tester
  • The quality class of the concrete cover of dry concrete can be read from a table using the kT value
  • In the case of moist concrete, kT is combined with electrical concrete resistance ρ (rho) and the quality class is determined from a nomogram
  • Optional resistance Wenner-probe to correct the influence of concrete moisture is available with the permeability tester.


  • The Torrent permeability tester determines the quality of concrete cover
  • The Torrent permeability tester assesses the durability of a concrete structure


The following standards can be applied to the permeability tester:

  • SN 505 252/1, Annex E
