SOIL HYDROMETER AZA0858
AZA0858 – Reliable Soil Hydrometer for Fine Particle Analysis
The AZA0858 Soil Hydrometer from AZA Lab is a precision glass instrument designed for grain size analysis of fine-grained soils using the sedimentation (hydrometer) method. It is specifically intended for soils in which more than 10% of the material passes through the 75-micron sieve, ensuring accurate assessment of clay and silt fractions in accordance with internationally recognized standards.
Manufactured from high-clarity transparent borosilicate glass, the AZA0858 features a permanently engraved density scale for direct, reliable readings of suspension density over time. The instrument is factory calibrated and optimized for use at 27°C, delivering high precision in both laboratory and controlled field testing environments.

Frequently Asked Questions (FAQ)
Q1: What does the AZA0858 Soil Hydrometer measure?
It measures the density of a soil–water suspension during sedimentation testing to determine the grain size distribution of fine soil particles.
Q2: Can this hydrometer be used for coarse soils?
No. It is intended only for fine particles passing the 75 µm sieve. Coarse soils should be analyzed using sieve methods.
Q3: Is the hydrometer supplied calibrated and ready for use?
Yes. Each unit is factory calibrated and supplied with a permanently engraved density scale.
Q4: Can it be used with liquids other than water?
Yes. Custom-calibrated versions for oils or other liquids can be supplied upon request.
Q5: Is the AZA0858 suitable for field laboratories?
While primarily designed for laboratory use, it can be used in field labs provided proper handling and temperature control are maintained.

INFRARED MOISTURE METER AZA0875
The AZA0875 Infrared Moisture Meter from Azalab is a high-precision analytical instrument designed for fast, accurate moisture content determination across a wide range of materials. Utilizing advanced infrared (halogen) heating technology, the AZA0875 significantly reduces analysis time compared to conventional oven-drying methods, delivering reliable results within minutes.
This instrument is ideally suited for geotechnical laboratories, construction quality control, chemical and pharmaceutical industries, food processing, and material testing laboratories, where rapid and repeatable moisture data is essential for process control and compliance.
LINEAR SHRINKAGE MOULD AZA0850
The AZA0850 Precision Linear Shrinkage Mould from AZALAB is a compact and highly accurate laboratory instrument designed for determining the linear shrinkage of fine-grained cohesive soils in accordance with BS 1377-2. This test is a key component of soil classification and is especially important in identifying shrink–swell behavior of clays and expansive soils.
Linear shrinkage testing measures the reduction in length of a soil specimen upon drying, expressed as a percentage of its original length. The results provide valuable insight into soil expansiveness, volume stability, and suitability for foundations, pavements, and earthworks.
Manufactured from high-quality brass or stainless steel, the AZA0850 mould offers precise internal dimensions, excellent corrosion resistance, and a smooth polished finish for easy sample preparation and removal. Its robust construction ensures repeatable, reliable results even under high-frequency laboratory use.
LIQUID LIMIT DEVICE WITH COUNTER AZA0853
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.

SOIL CONE PENETROMETER AZA0851
Principle of Operation
A soil paste prepared at a known moisture content is placed in the sample cup. The stainless steel cone, of specified mass and angle, is allowed to penetrate the soil freely for 5 seconds. The depth of penetration (up to 20 mm) is measured using a precision depth gauge. The moisture content corresponding to 20 mm penetration is defined as the liquid limit of the soil.Standards Compliance
