Cross Permeability Test Apparatus
Product Code : JA-GT-9860
The Cross Permeability Test Apparatus (SKU JA-GT-9860) measures the permeability of a geotextile across its plane - the volumetric flow of water per unit area under unit hydraulic head. It provides both constant head and falling head permeameters; the constant head test uses a 50 mm head of water on a 100 mm diameter specimen. A geotextile must be much more permeable than the soil it protects, so water passes without building up pressure. It is supplied by JaincoLab for geosynthetics and civil engineering laboratories.
Specifications
The apparatus includes constant head and falling head permeameters for 100 mm diameter specimens, with a 50 mm water head for the constant head test; permeameter construction and accessories are not listed in the product data and are confirmed on the quotation.
