SOIL PERMEABILITY APPARATUS

Falling Head Permeability Apparatus

Product Code  :   MSI 3030

Standard Used :  IS 2720 (Part 17) 1966 

Formally standardized for the laboratory determination of the coefficient of permeability of soils using constant or variable head methods.

Product Description
The Multitech Scientific Instruments MSI 3030 Permeability Apparatus is a high-precision laboratory testing assembly designed to determine the coefficient of permeability of fine-grained and semi-pervious soil structures. Configured for both constant-head and falling-head (variable-head) methodologies, this apparatus is highly recommended for evaluating soils with a coefficient of permeability falling in the specific range of 10⁻³ to 10⁻⁷ cm/sec. The engineered compaction mould safely accommodates soil mixtures containing a maximum particle size of 10 mm, providing geotechnical and civil engineering testing centers with highly repeatable and accurate hydraulic conductivity data.

• Features

  • Precision-Graduated Standpipe Unit: Outfitted with clear glass standpipes of varying internal diameters mounted on a structural frame to precisely track variable head drops over timed intervals.

  • Heavy-Duty Permeability Mould: Machined from high-grade, anti-corrosive brass or gunmetal with tight-fitting sealing rings to prevent any sidewall leakage during high-pressure fluid flow.

  • Integrated Drainage Accessories: Supplied with premium porous discs and perforated plates designed to distribute water uniformly across the soil boundaries without washing away fine particles.

  • Dual Testing Versatility: Fully adjustable plumbing design that allows laboratory technicians to alternate seamlessly between variable (falling) head and constant head testing configurations.

• Application

  • Used to calculate the hydraulic conductivity and seepage rate of compacted clay, silt, and fine sand layers.

  • Essential for evaluating the drainage characteristics of earthen dam cores, retaining wall backfills, and highway subgrade soils.

  • Extensively utilized by central soil mechanics boards, third-party quality assurance consultants, and university civil engineering departments.

• Technical Specifications

  • Reference Standard Guideline: IS 2720 (Part 17) 1966.

  • Recommended Test Spectrum: Permeability coefficients ranging from 10⁻³ cm/sec to 10⁻⁷ cm/sec.

  • Maximum Material Aggregation Size: Up to 10 mm.

  • Mould Composition: Premium-grade brass or specialized gunmetal alloy.
