Proceq Torrent
Permeability Tester

 

The Proceq 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 Torrent permeability tester takes 2-12 minutes. .

Proceq Torrent Permeability Tester

The particular features of the TORRENT method are a two-chamber vacuum cell and a pressure regulator, which ensure that an air flow at right angles to the surface is directed towards the inner chamber. This permits the calculation of the permeability coefficient kT on the basis of a simple theoretical model.

The unit has a user-friendly menu technique and measures the pressure increase as a function of time according to a specific sequence. The associated data is automatically collected by the display unit and the permeability coefficient kT and the depth of penetration L of the vacuum are calculated.

The measurement takes 2-12 minutes, depending on the permeability of the concrete. In the case of dry concrete, the quality class of the concrete cover can be read from a table using the kT value. In the case of moist concrete,
