Product Description
The Geotextile Water Permeability Tester, crafted with precision to align with the latest national standard GB/T15789-2005 and the authoritative SL235 water resources standard, stands as a paragon of innovation in laboratory testing instruments. It is expertly designed for evaluating a range of geotextiles and composite fabrics with superior water permeability, specifically to determine vertical permeability under a consistent water head. This state-of-the-art machine features microcomputer program control for seamless operation, along with sensor-driven data acquisition and measurement. It offers digital setting of head difference, automatic positioning, and the effortless conversion of the permeability coefficient, complemented by comprehensive display, storage, and statistical capabilities, as well as editing and printing functions for a complete testing solution.
Standard
GB/T15789-2005, SL/T235-2012 ASTM D4491-2017 method A- constant head test |
Principle
The core principle involves measuring the flow velocity of water as it moves perpendicular to the geotextile's plane under a unit hydraulic gradient, expressed in millimeters per second (mm/s).
