Pocket Concrete Penetrometer
Pocket Concrete Penetrometer (Product Code: SLE/CE/33) is a hand-held spring penetrometer used to measure the penetration resistance of concrete mortar and judge when it reaches initial set, in concrete laboratories and during site quality checks. Its direct-reading scale runs from 0 to 50 kg/cm², a marker ring holds the reading after release, and concrete is assumed initially set once resistance reaches 35 kg/cm². It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

What Is a Pocket Penetrometer Used For?
As concrete stiffens, the mortar offers more and more resistance to a pointed needle. The pocket penetrometer turns that resistance into a number: the needle is pressed steadily into the mortar, the calibrated spring compresses, and the marker ring slides along the scale and stays at the maximum value when the instrument is withdrawn. Tracking readings over time shows when the concrete approaches initial set.
Site engineers and laboratory staff use this information to time finishing work, compare mixes with and without admixtures, and demonstrate setting behaviour to students. Press the needle at a steady rate, test fresh spots each time, reset the marker ring before every reading, and wipe the needle clean before returning it to its carrying case. Its small size makes it a convenient addition to the engineering lab equipment kit of a college or site laboratory.
OEM Manufacturer
This Pocket Concrete Penetrometer is an original ScienceLab product: Jain Scientific Equipments Private Limited, trading as ScienceLab, is its OEM and manufactures it at the company's own licensed factory in Saha, Ambala, Haryana. Institutions, contractors' laboratories, dealers and importers buy it factory-direct, and repeat orders or spare parts can be requested from the manufacturer itself — just ask us.

Frequently Asked Questions
What does the Pocket Concrete Penetrometer measure?
The Pocket Concrete Penetrometer measures the penetration resistance offered by concrete mortar to its needle. The value is shown on a direct-reading scale of 0 to 50 kg/cm² and is used to follow the stiffening of concrete and judge when initial set has been reached.
At what reading is concrete considered initially set?
With the Pocket Concrete Penetrometer, concrete is assumed to be initially set when the penetration resistance reaches 35 kg/cm². Taking readings at regular intervals shows how quickly the mix is approaching that point, which helps plan finishing and other time-sensitive work.
How does the marker ring work?
The marker ring on the Pocket Concrete Penetrometer is pushed along the scale as the spring compresses and holds its position when the instrument is released. The operator can therefore withdraw the needle and read the maximum resistance calmly, then slide the ring back before the next test.
How large is the pocket penetrometer?
The Pocket Concrete Penetrometer measures 178 × 19 mm and has a needle face area of 3/10 sq cm. The needle point is an integral part of the barrel that houses the calibrated spring, and the instrument is supplied complete in a carrying case.
Who manufactures the Pocket Concrete Penetrometer?
The Pocket Concrete Penetrometer (SLE/CE/33) is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Orders and enquiries are handled by the manufacturer directly.
Is a spring calibration certificate available?
If you need a calibration or inspection document for the Pocket Concrete Penetrometer, please discuss it with us before ordering so we can confirm what can be supplied. Add the requirement to your enquiry on the contact page.
Can the penetrometer be ordered in bulk?
Yes, the Pocket Concrete Penetrometer can be quoted for single units or larger quantities for colleges, contractors and dealers in India and international markets. State the quantity and delivery location in your enquiry so the manufacturer can prepare an accurate quotation.
