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 Torrente 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 ? (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
