Description

Compact Pocket Pentrometer – ASTM D1558 D2573

The Compact Pocket Penetrometer from azalab is a field-ready device designed for quick estimation of unconfined compressive strength (UCS) and shear strength in cohesive soils. Fully compliant with ASTM D1558 and ASTM D2573, it allows engineers, geologists, and site inspectors to assess soil consistency and stability rapidly—without the need for complex lab equipment.aza

Commonly used in foundation evaluation, trench wall inspection, and field soil classification, this penetrometer is a reliable and convenient tool for cohesive soils such as clays and silts.aza

Applications

Estimating UCS and shear strength of soft to stiff clays
Field classification of soil consistency
Pre-construction soil stability checks
Slope stability and shallow foundation planning
Soil research and academic fieldwork

How It Works

Press the loading piston into the freshly exposed soil surface.
The engraved scale on the barrel shows the force applied in kg/cm².
The maximum load indicator ring retains the peak value reached.
Use the reading to estimate UCS or shear strength directly.

This tool provides instant results and is widely accepted for preliminary geotechnical assessments.

FREQUENTLY ASKED QUESTIONS (FAQ)

Q1: What soil types is this tool suitable for?
It is ideal for cohesive soils such as clays and silts. Not suitable for gravelly or dry sandy soils.

Q2: What does the scale measure?
It directly shows pressure in kg/cm², correlating to the unconfined compressive strength of the soil.

Q3: Does it require calibration?
It is factory-calibrated. For critical use, periodic verification using known load weights is recommended.

Q4: Is the spring protected from corrosion?
Yes, the heat-treated spring is plated for rust resistance, ideal for rugged outdoor conditions.

Q5: How is it transported?
The penetrometer comes in a compact, protective carrying case, perfect for field kits.
