Import Constant Head Permeability Sets — Buy in Bulk from Supplier in Turkey

The Constant Head Permeability Sets from Parsros Material Testing Equipment are designed for laboratory testing of soil permeability in coarse-grained materials such as sands and gravels. Two models are available: PRS-ZE1300 for an 80 mm diameter cell and PRS-ZE1301 for a 120 mm diameter cell. Each cell features an acrylic glass body with three pressure points at distinct vertical levels to measure hydraulic gradients accurately. The system includes a wooden stand with three 1000 mm glass manometer tubes and a 7 L transparent plastic constant-level water tank to maintain steady head conditions during testing.

The permeability cells are supplied with two wire gauzes matched to the selected diameter, ensuring proper sample containment without clogging. The standard setup includes a 3 m hose for water flow and a tamping rod measuring 8 mm in diameter and 300 mm in length, used for compacting soil samples to consistent density. These components adhere to BS 1377:5 standards for soil permeability testing. The acrylic glass construction ensures clarity for visual observation, while the pressure points allow precise measurement of head loss across the sample. The system does not include de-airing equipment, which must be ordered separately.

These sets are primarily purchased by geotechnical laboratories, university civil engineering departments, and independent soil testing firms conducting research on infiltration rates and drainage behavior. Buyers typically require the 80 mm cell for standard compliance testing and the 120 mm cell for larger samples or research applications. The complete system is shipped disassembled for safe transport, with each component labeled by product code. Trade terms are FOB Istanbul or as negotiated; lead times are typically 2 to 3 weeks after order confirmation.
