Kombine Sabit ve Düşen Baş Aparatı

Combined Constant and Falling Head Apparatus is designed to determine the coefficient of permeability of soil specimens in laboratory conditions. The system offers two testing methods in a single unit, allowing reliable evaluation of both low-permeability and high-permeability soils.

The falling head method—used for fine-grained soils—calculates the permeability coefficient based on the reduction of water level over time, while the constant head method—preferred for coarse-grained, highly permeable soils—provides accurate results by measuring flow rate under a constant hydraulic head. Manufactured from durable, corrosion-resistant materials, the apparatus offers long service life as well as easy installation. Precision measurement tubes and a modular design provide flexibility, ease of use, and dependable performance.
