The field saturated hydraulic conductivity (Kfs) or permeability of in situ soil and constructed fill materials can be quickly and easily measured “in-place” using the ETC Pask Constant Head Permeameter.

The ETC Constant Head Permeameter

convenient and Cost effective alternative to other types of in situ permeameters such as the Guelph Permeameter®


The ETC Constant Head Permeameter is a much faster and more accurate method of assessing the hydraulic capacity of a soil than the outdated, and often very time consuming, percolation test.
Check this blog article for a detailed 20 point comparison of the ETC Pask Permeameter to the Guelph Permeameter.
The ETC Pask Permeameter works with almost any soil type from loams and sands to clays, even built-up beds of imported septic fill or compacted clay liners for lagoons and landfills.
Our permeameter is based on the peer-reviewed, Constant Head Well Permeameter method, described by Reynolds and Elrick, formerly of the University of Guelph, Canada.

    La simplicité du perméamètre PASK le rend facile à utiliser et à transporter en plus d’être à bon prix. Il est actuellement le meilleur produit disponible sur le marché.

    Translation: The simplicity of the PASK permeameter makes it easy to use and carry, in addition to being at the right price. It is currently the best product on the market.


    J'utilise le perméamètre de Pask depuis maintenant 6 mois et je suis très satisfait de la technologie et de l'équipement. En effet, les résultats sont reproductibles et l'équipement facile à manipuler et à utiliser. Le coût moindre de l'équipement m'a permis d'équiper tous les techniciens de leur propre perméamètre permettant ainsi une meilleure efficience dans la réalisation des essais de conductivité hydraulique. Vous pouvez définitivement recommander à vos futurs clients d'acheter cet appareil.

    Salutations distinguées,

    Translation: I have been using the Pask Permeameter for 6 months now and I am very satisfied with the technology and equipment. Indeed, the results are reproducible and the equipment is easy to handle and use. The cost of the equipment allowed me to equip all of the technicians with their own permeameter enabling greater efficiency in carrying out hydraulic conductivity tests. You can definitely recommend to your future customers to buy this product.
