POCKET PENTROMETER AZA0869

The AZA0872 Dynamic Cone Penetrometer (DCP) from Azalab is a robust, field-proven instrument designed for rapid in-situ evaluation of soil strength, stiffness, and compaction. It is extensively used by civil engineers, geotechnical consultants, and construction teams for pavement design, quality control, and site investigation works.

The DCP test provides a fast and economical method to assess the strength of subgrades, sub-bases, and granular base course layers, with results that can be directly correlated to California Bearing Ratio (CBR) values. This eliminates the need for time-consuming laboratory testing or undisturbed soil sampling, enabling immediate decision-making at site.

The AZA0860 Methylene Blue Test Set from AZA Lab is a comprehensive laboratory system designed to determine the clay content and clay activity in fine aggregates and soils through measurement of the Methylene Blue Value (MBV). The test is highly sensitive to active clay minerals—particularly montmorillonite—that can adversely affect the performance of concrete, asphalt, and other construction materials. This method is widely adopted in aggregate quality control, concrete mix design, asphalt technology, and geotechnical investigations, providing a reliable indicator of fines reactivity and cation exchange capacity.

• UNE 83 180
• UNI 8520-15
• ASTM C837 – Methylene Blue Index of Clay in Fine Aggregate

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.

The Vicksberg Penetrometer (Proving Ring Type) – AZA0870 by Azalab is a precision-engineered field instrument designed to determine the bearing capacity of subgrades, assess soil compaction levels, and conduct rapid shallow soil investigations. It is widely used in road construction, foundation assessment, and infrastructure site inspections where quick, reliable field results are required.

Designed for efficient single-person operation, the instrument incorporates a 100 kg (1 kN) proving ring combined with a high-sensitivity dial gauge of 0.002 mm least count, ensuring accurate and repeatable load measurements. An optical viewer is provided for clear dial visibility, even under bright outdoor conditions, making the unit ideal for on-site testing.

Whether for routine site investigations or quality control of compacted layers, the AZA0870 delivers fast, dependable, and field-ready performance.
