Soil Cone Penetrometer (Manual Model)

Product Code : MSi 3004

Standard Used  : IS 2720 (Part 5) | Formally standardized for the determination of liquid limit of soils, aligning with Indian Road Congress (IRC) and BIS specifications.

Product Description
The Multitech Scientific Instruments Soil Cone Penetrometer is a high-precision laboratory instrument designed to establish the liquid limit of fine-grained soils. Unlike traditional dynamic methods, this cone penetration apparatus relies on a static gravity drop, making it an invaluable tool for civil engineering and soil mechanics laboratories. It is specifically engineered to deliver highly reproducible, operator-independent liquid limit determinations, eliminating human error during sample groove-scoring.

Features

• • Precision Dial Gauge: Features a large 150 mm diameter dial with a 0.1 mm resolution, tracking up to 400 divisions for micro-accurate depth profiling.

  • Frictionless Plunger Assembly: A micro-polished, ultra-smooth sliding rod ensures zero resistance during free-fall release.

  • Leveling Alignment: Built on a heavy, robust cast iron base equipped with adjustable leveling feet and a sensitive spirit level bubble to eliminate tilted drops.

  • Hardened Stainless Steel Cone: A 30 mm long, polished cone engineered to resist wear and maintain structural dimensions over thousands of test cycles.

  • Friction-Free Clutch: Smooth mechanical release mechanism designed to drop and lock the sliding weight precisely on time.

Application

• • Used to determine the Liquid Limit (LL) of fine-grained agricultural, foundational, and highway subgrade soils.

  • Low Plasticity Index Soils: Especially critical and highly recommended for testing silty soils and low-plasticity clays where the traditional Casagrande groove-closure method routinely slumps, slides, or fails to give reliable results.

  • Deployed across engineering colleges, private quality-control labs, infrastructural project sites, and highway construction projects.

Technical Specifications

• • Included Cone Angle: 30° ± 1° (equivalent to a highly accurate half-angle of 15° with a 15–30 minute tolerance constraint).

  • Total Sliding Weight: 148 grams ± 0.1g (comprising the precision cone, sliding rod, and standard calibration mass).

  • Target Penetration Depth: 25 mm (the percentage moisture content that yields exactly 25 mm penetration defines the liquid limit).

  • Soil Container Cup Dimensions: 50 mm Internal Diameter × 50 mm Depth (Heavy brass/stainless steel construction).
