AZA 1114 POCKET CONCRETE PENETROMETER

Description

Pocket Concrete Penetrometer is a compact, field-grade testing instrument used to determine the initial and final setting times and early strength of fresh concrete and mortar mixes. At Azalab, we supply precision-calibrated penetrometers ideal for site engineers, quality control teams, and lab technicians who need quick and reliable insights into concrete performance during the early curing stages.

This small but essential tool operates on a spring-loaded plunger mechanism, which penetrates the concrete or mortar surface under a calibrated force. The depth of penetration is directly related to the material’s stiffness or resistance, and the corresponding force is read on a graduated scale in either MPa (megapascals) or psi (pounds per square inch).

Azalab’s Pocket Concrete Penetrometer conforms to ASTM C403 and IS 8142 standards, making it suitable for professional testing of:

• Setting time of concrete

• Early strength gain of cement-based materials

• Workability assessment during placement

• Field control of curing conditions

The device features a stainless steel body and ergonomically knurled grip for safe, one-hand operation. The plunger diameter (usually 6.4 mm) and spring resistance are precisely manufactured and factory-calibrated to provide repeatable readings. Most models cover a strength range from 0.1 MPa to 7 MPa (15 psi to 1000 psi), which corresponds to the typical early strength range of mortar and concrete during the first few hours after mixing.

The test procedure involves pressing the plunger into the concrete or mortar surface at regular intervals and recording the resistance force. By plotting the penetration resistance versus time, engineers can estimate:

• Initial set: When concrete starts to resist load

• Final set: When concrete becomes sufficiently stiff to bear light loads

The pocket concrete penetrometer is widely used in:

• Road and pavement construction projects

• Precast concrete manufacturing

• Shotcrete and sprayed mortar applications

• Cement additive and admixture research

• Remote field locations where lab setups are unavailable

Each penetrometer from Azalab is supplied in a foam-lined protective case, along with a conversion chart, user manual, and factory calibration certificate. Optional models are available with replaceable plungers, digital dial gauges, or indicator markers to ensure peak-reading capture.

Routine maintenance includes wiping the plunger clean after each use and verifying calibration annually or after accidental impact. Despite its compact size, this tool provides a strong indication of material development and is often used to validate curing times before formwork removal, loading, or finishing operations.

To understand proper penetration resistance test methods, refer to the full ASTM C403/C403M Standard, which details procedures for mortar and concrete stiffening time measurement.

With the Azalab Pocket Concrete Penetrometer, engineers get a fast, field-ready solution to assess concrete setting behavior. Its portability, compliance, and reliability make it a must-have device for modern construction testing.
