Introduction
Geo-synthetics vertical water penetration instrument is used to determine the geotextile and its related products in the constant head of the vertical permeability. The instrument's head can be adjusted (0-300mm), and can maintain a stable head. The instrument uses a box structure to reduce head loss.

Applications
Geo-synthetics vertical water penetration instrument is used to determine the geotextile and its related products in the constant head of the vertical permeability.

Standards:
ISO 11058 Geotextiles and geotextile-related products — Determination of water permeability characteristics normal to the plane, without load
