LIQUID LIMIT DEVICE (MOTORISED)

Motorised Liquid Limit Device

Product Code l: MSI 3007)

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

Precision-engineered to satisfy global engineering standards for motorized Casagrande soil mechanics and foundational shear-strength evaluation.

Product Description
The Multitech Scientific Instruments MSI 3007 Motorised Liquid Limit Device takes the classic Casagrande method and automates it for high-frequency testing environments. This advanced laboratory unit is fitted with a specialized geared motor that delivers a uniform rate of drop, completely removing human variance in cranking speed. It is ideal for tier-1 civil engineering laboratories, commercial soil testing firms, and government infrastructure projects where strict test pacing and zero human error are mandatory.

• Features

  • Automated Geared Motor Drive: Driven by a precision motor geared down to maintain a constant speed, eliminating operator exhaustion and manual inconsistencies.

  • Standardized Blow Rate: Operates at a highly controlled, standardized frequency of approximately 120 RPM (2 blows per second).

  • Mechanical Counter Integration: Includes a durable auto-registering blow counter that accurately tracks every single impact of the cup.

  • Heavy-Duty Rubber Impact Base: Molded from vulcanized hard rubber with regulated rebound hardness parameters to avoid uncalibrated energy absorption.

  • Industrial Power Compatibility: Wired out of the box for immediate integration into standard laboratory electrical grids.

• Application

  • Designed for high-volume Liquid Limit (LL) evaluation where hand-cranking becomes inefficient.

  • Used to calculate the baseline Plasticity Index (PI), soil settlement behavior, and structural compressibility indices.

  • Deployed across mega-infrastructure project sites, highway quality-assurance labs, and university soil mechanics research facilities.

• Technical Specifications

  • Drive Mechanism: Geared electric motor system.

  • Operating Speed: Approximately 120 RPM.

  • Electrical Rating: 230 V A.C., Single Phase, 50 Hz cycle operations.

  • Cup Assembly: Polished brass cup held securely on an adjustable cam bracket.

  • Drop Threshold: Pre-calibrated 1 cm (10 mm) high-impact fall mechanism.

• Available Spares & Accessories

  • Casagrande Grooving Tool: Precision tool for scoring standard Indian and British standard soil pastes.

  • ASTM Grooving Tool: Standardized tool for American alignment and regulatory compliance.

  • Height Gauge Block: Calibrated 1 cm high block used to periodically verify and adjust the exact drop height of the brass cup.
