Concrete Penetrometer Spring Type
Concrete Penetrometer Spring Type (Product Code: SLE/CE/23) is a spring-loaded penetration device used to find the rate of hardening of mortar sieved from fresh concrete in concrete testing laboratories and on site. Technicians press one of its six interchangeable needles 25 mm into the mortar and read the force from a sliding ring on the graduated stem. Jain Scientific Equipments Pvt Ltd (ScienceLab) makes it as the OEM at its own factory in Ambala, India, as part of its engineering lab equipment in India range.

What Is the Concrete Penetrometer Used For?
Mortar is sieved out of a fresh concrete sample and placed in a container. At regular intervals a needle is pushed into the mortar to a depth of 25 mm — two of the 12.5 mm marks on the shank — and the sliding ring records the force reached. Dividing that force by the needle area gives penetration resistance, and plotting it against elapsed time shows how quickly the concrete is setting.
Start with the largest needle while the mortar is soft and change to smaller needles as it stiffens, so the force stays within the scale. Reset the sliding ring before each reading and wipe the needle clean. The results help plan finishing, formwork removal and the effect of admixtures in hot or cold weather.
What to Specify When Ordering
- The load scale you need: 1–100 daN, or a stem graduated 0–70 kg × 1 kg.
- The number of penetrometers for your laboratory or site teams.
- Any sieve needed to separate mortar from the concrete sample, and other setting-time equipment to quote together.

Frequently Asked Questions
What is the Concrete Penetrometer Spring Type used for?
The Concrete Penetrometer Spring Type is used to find the rate of hardening of mortar sieved from fresh concrete. It measures the force needed to push a needle 25 mm into the mortar at intervals, showing how the setting of the concrete progresses.
How many needles come with the Concrete Penetrometer Spring Type?
The Concrete Penetrometer Spring Type is supplied with six interchangeable penetration needles, with bearing areas listed as approximately 645–650, 323–325, 160, 65, 32 and 16 mm². The needle shanks are marked at every 12.5 mm.
How is the reading taken on the Concrete Penetrometer Spring Type?
On the Concrete Penetrometer Spring Type, the needle is pressed 25 mm into the mortar and a sliding ring on the graduated stem stops at the maximum force reached. Penetration resistance is that force divided by the needle area.
Which load scale does the Concrete Penetrometer Spring Type have?
The Concrete Penetrometer Spring Type is listed with a spring scale graduated from 1 to 100 daN, and the listing also mentions a stem graduated 0–70 kg × 1 kg. Confirm the scale you need in your enquiry.
Who manufactures the Concrete Penetrometer Spring Type?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Concrete Penetrometer Spring Type as the OEM at its licensed factory at Saha, Ambala, Haryana, India, and supplies it directly to laboratories, institutions, dealers and importers.
Is a calibration certificate available for the Concrete Penetrometer Spring Type?
Ask us before ordering: whether a calibration certificate can be provided for the Concrete Penetrometer Spring Type is confirmed case by case. Note the requirement in your enquiry through the contact page and it will be answered in the quotation.
What is supplied with the Concrete Penetrometer Spring Type?
The Concrete Penetrometer Spring Type comes complete with its six interchangeable needles and a carrying case, and weighs approximately 5 kg. The case keeps the spring device and needles together for site and laboratory use.
