Geotextile Vertical Water Permeability Tester
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
