This test kit is an essential component of geotechnical investigations, civil engineering projects, and soil mechanics laboratories, providing reliable and repeatable results in both laboratory and field environments. Purpose & Importance The plastic limit represents the lowest moisture content at which soil remains plastic and can be rolled into threads of 3 mm diameter without crumbling. Determination of this limit is critical for:
  • Soil classification (Atterberg limits)
  • Assessing workability and consistency
  • Evaluating shrink–swell characteristics
  • Supporting foundation, pavement, and earthwork design

PLUMMET BALANCE AZA0862

The AZA0862 Plummet Balance is a specialized laboratory apparatus designed for determining the specific gravity of fine-grained soils, particularly clays and silts that are difficult to test using conventional pycnometer methods. It is widely used in geotechnical engineering, soil mechanics laboratories, and construction quality control applications. Manufactured by Azalab, the instrument complies with ASTM D854 and IS 2720 (Part 3 / Sec 1) standards and provides rapid, repeatable, and reliable results for dispersed soil samples commonly used in sedimentation, pipette, and hydrometer analyses.
Working Principle The plummet balance method determines the specific gravity of soil solids by measuring the apparent weight of a suspended plummet immersed in a soil–water suspension. The balance pointer directly indicates the percentage of soil in suspension via a calibrated scale, eliminating lengthy calculations. A rack-and-pinion height adjustment allows the plummet to be positioned at the required depth. The percentage of soil in suspension is read directly from the graduated scale, making this method faster and more user-friendly than traditional sedimentation calculations. The set is supplied with a temperature correction chart relating the constant K to suspension temperature for soils with specific gravity ranging from 2.4 to 2.8, facilitating accurate application of Stokes’ law.

SAND EQUIVALENT TEST SET AZA0859

The AZA0859 Sand Equivalent Test Set from AZA Lab is a standardized laboratory and field testing apparatus used to determine the relative proportion of sand versus clay-like or plastic fines in fine aggregates and granular soils. This test is critical in construction quality control where aggregate cleanliness directly affects the performance of asphalt pavements, concrete mixes, and base course layers. The test set conforms to ASTM D2419, IS 2720 (Part 37), and AASHTO T176, ensuring accurate, repeatable, and specification-compliant results. The Sand Equivalent Value (SEV) provides a simple numerical indication of aggregate quality by comparing the height of settled sand to the height of clay suspension after sedimentation.
Working Principle A prepared fine aggregate sample is placed in a graduated cylinder and mixed with a standard calcium chloride-based solution. After agitation and a controlled settling period, heavier sand particles settle at the bottom while lighter clay and silt particles remain in suspension. The Sand Equivalent Value (SEV) is calculated as: SEV = (Height of Sand / Height of Clay Suspension) × 100 Higher SEV values indicate cleaner aggregates with lower clay contamination, which are preferred for structural and pavement applications.

SEMI AUTOMATIC CONE PENETROMETER AZA0852

The AZA0852 Semi Automatic Cone Penetrometer from AZALAB is a precision-engineered laboratory instrument used for determining the liquid limit and consistency characteristics of fine-grained soils. Designed to eliminate operator-dependent errors, this semi-automatic model ensures uniform cone release and repeatable penetration results, making it an ideal choice for geotechnical, civil engineering, and construction material testing laboratories. The apparatus conforms to IS 2720 (Part 5) and BS 1377 standards and is widely used for soil classification, foundation assessment, and settlement analysis. Its semi-automatic clutch-based drop mechanism allows the cone to penetrate the soil sample under controlled conditions for a fixed duration of 5 seconds, ensuring consistent and reliable test outcomes.

Principle of Operation

A soil paste prepared at known moisture content is placed in the sample cup. The standardized cone, attached to a calibrated weight, is released using the semi-automatic clutch mechanism, allowing free fall penetration into the soil. After the specified time (typically 5 seconds), the penetration depth is measured using a high-precision dial gauge. The moisture content corresponding to a penetration of 20 mm is considered the liquid limit of the soil, as defined in IS and BS standards.
