SPLIT SPOON SAMPLER AZA0918
The AZA0918 Split Spoon Sampler is a precision-engineered soil sampling device used for collecting relatively undisturbed subsurface soil samples during Standard Penetration Tests (SPT) and other geotechnical investigations. Its split-barrel construction enables easy opening, inspection, and removal of the soil core without disturbing its natural structure, making it ideal for laboratory classification and strength evaluation.
AZA0918 is routinely deployed in boreholes as part of SPT procedures, where it is driven into the soil using a standard drop hammer. The number of hammer blows required to advance the sampler provides critical data on soil density, consistency, and bearing capacity in accordance with ASTM D1586.

SEMI AUTOMATIC CONE PENETROMETER AZA0852
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.
