Pressure take-off ports are positioned at a fixed spacing along the specimen height for accurate measurement of hydraulic head loss. Internal retaining grooves and fine stainless mesh screens (\u2248100 mesh) prevent particle migration while maintaining uniform flow. A spring-loaded seating element located on the top cap maintains consistent contact between the permeameter screen and the specimen surface, ensuring uniform confinement throughout the test. All wetted components are selected for corrosion resistance, and the cell is supplied with integral valves, air-release fittings, and quick-connect plumbing compatible with manometer stands and piezometer lines. The system is available in a range of specimen diameters \u2014 63, 76, 114, 152, and 229 mm \u2014 to accommodate various material gradations and test requirements. The permeameter is fully compatible with constant head tanks, differential manometer assemblies, flexible tubing, and de-airing modules; falling-head accessories may also be integrated using the same base frame when alternative test configurations are required.<\/p>","protected":false},"excerpt":{"rendered":"

Constant Head Permeability Set (ASTM) is designed to accurately evaluate the hydraulic conductivity of granular and cohesionless soils under controlled laboratory conditions. The permeameter assembly utilizes rigid-wall cells manufactured from impact- and corrosion-resistant materials. Precision-machined upper and lower caps with O-ring seals ensure leak-free operation, allowing the applied head to propagate through the specimen in a stable, laminar flow regime. Dimensions and port configurations comply with ASTM D2434 and relevant highway authority specifications.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[128,119],"product_tag":[],"class_list":{"0":"post-11268","1":"product","2":"type-product","3":"status-publish","5":"product_cat-soil-permeability","6":"product_cat-soil-lab","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"yoast_head":"\nConstant Head Permeability Set, ASTM -
