LIQUID LIMIT DEVICE WITH COUNTER

Liquid Limit Device with Counter

Product Code : MSI 3006

• Standard Used : IS 2720 (Part 5) | BS 1377-2 | ASTM D4318 

 Full compliance with global standards governing mechanical soil mechanics, soil classification, and foundational engineering metrics.

• Product Description
  The Multitech Scientific Instruments MSI 3006 Liquid Limit Device with Counter is a foundational laboratory testing apparatus used to perform the mechanical Casagrande method. Used for decades in modern soil mechanics, this instrument precisely measures the exact water content at which a soil sample transitions from a liquid state to a plastic state. At this critical threshold, the soil exhibits an approximate shear strength of 0.17 N/cm² (17 gms/sq.cm.). Because determining the true absolute limit is physically impossible as strength transitions towards zero, this apparatus standardizes empirical evaluation by tracking the impact of a calibrated 1 cm drop on a standard hard-rubber base.

• Features

  • Integrated Blow Counter: Features a heavy-duty mechanical counter that registers every single blow automatically, eliminating operator miscounts.

  • Precision Cam Action: Engineered with a specialized cam mechanism that smoothly raises and drops the brass cup without jerking or sliding.

  • Adjustable Drop Bracket: Outfitted with an easy-to-calibrate drop adjustment system to maintain a flawless 1 cm drop height.

  • Standard Hardness Rubber Base: Molded from vulcanized rubber with strict adherence to rebound hardness standards to avoid false energy absorption.

  • Dual Grooving Tool Capability: Shipped as a complete kit supporting both Indian, British, and American testing methods simultaneously.

• Application

  • Used to calculate the Liquid Limit (LL) required to derive the Plasticity Index (PI) and Compressibility profiles of structural soils.

  • Essential for predicting the settlement, load-bearing capability, and lower shear strength properties of highway subgrades and building foundations.

  • Extensively utilized by quality-assurance inspectors, geotechnical engineering consultants, academic institutes, and tier-1 construction laboratories.

• Technical Specifications

  • Cup Material: Premium-grade polished brass.

  • Drop Height: Fixed calibration at exactly 1 cm (10 mm) using the included gauge block.

  • Base Composition: Specially vulcanized resilient hard rubber base block.

  • Test Criteria: Designed to record the water percentage at which a standard soil groove flows together for a distance of 1.25 cm under an impact of 25 blows.

  • Standard Accessories Included: 1 × Casagrande Grooving Tool, 1 × ASTM Grooving Tool, and 1 × Machined Height Gauge Block.
