POCKET PENTROMETER AZA0869

The AZA0855 High Speed Stirrer from AZA Lab is a robust and versatile laboratory instrument designed for efficient mixing, homogenizing, and dispersion of liquids and semi-liquids. Engineered for mechanical analysis as well as general laboratory applications, it is ideal for research, analytical, academic, and industrial laboratories requiring precise and reliable stirring performance. Driven by a high-torque motor, the AZA0855 is capable of achieving high stirring speeds of approximately 4000 RPM under load, ensuring uniform blending, effective particle dispersion, and consistent results. The unit supports a dispersion cup mounted on a dedicated rest provided on the stirrer stand, complete with a removable baffle to enhance mixing efficiency and reduce vortex formation. Operating on 230V AC, the AZA0855 is suitable for continuous laboratory use and is supplied with a dispersion cup / baffle cup in accordance with AZA Lab design principles.

The AZA0853 Liquid Limit Device with Counter from AZALAB is a precision-engineered instrument used for determining the liquid limit of soils in accordance with the Casagrande method. This test is a fundamental component of soil classification and geotechnical investigation, providing critical insight into the plasticity, compressibility, and shear strength of fine-grained soils.

Designed for reliable, repeatable, and standardized testing, the AZA0853 is widely used in geotechnical laboratories, civil engineering departments, construction quality control labs, and academic institutions.

Principle of Liquid Limit Test (Casagrande Method)

The liquid limit is defined as the water content at which soil transitions from a plastic state to a liquid state. In practice, it is determined as the moisture content at which a standard groove cut in the soil sample closes over a length of 12.5 mm under 25 blows of the liquid limit apparatus.

The AZA0853 consists of a polished brass cup mounted on an adjustable bracket. The cup is repeatedly raised and dropped from a fixed height of 1 cm onto a hard rubber base by means of a manually operated cam mechanism. A built-in mechanical counter accurately records the number of blows, ensuring compliance with testing standards and reducing operator error.

The AZA0848 Plastic Limit Set is a standardized soil testing kit designed for the accurate determination of the plastic limit of fine-grained soils, in accordance with IS: 2720 (Part 5) and ASTM D4318. The plastic limit is a fundamental soil index property used in soil classification and in evaluating soil behavior under varying moisture conditions. 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

The AZA0848 set provides all required accessories to conduct the test accurately, efficiently, and in full compliance with applicable standards.

The AZA0873 Speedy Moisture ZI 3027 Meter (D2 Large) from Azalab is a high-performance field instrument designed for rapid and accurate determination of moisture content in soils, aggregates, sand, and similar materials. Based on the proven calcium carbide gas pressure method, this instrument is widely used in earthwork compaction control, road construction, geotechnical investigations, and concrete production, where immediate moisture data is critical for quality assurance.

The D2 Large configuration distinguishes the AZA0873 by allowing a larger sample size, providing more representative and reliable results, especially for heterogeneous materials and aggregates with larger particle sizes. Its rugged ZI 3027 construction ensures dependable performance under demanding site conditions.
