Concrete Test Hammer Schmidt Hammer N-Type
Concrete Test Hammer Schmidt Hammer N-Type (Product Code: SLE/CE/41) is a rebound-type test hammer used to assess the compressive strength characteristics of hardened concrete non-destructively in structural investigation, site quality-control and civil engineering teaching laboratories. Engineers use it to control the uniformity of concrete and detect weak spots in members, provided the test object is at least 100 mm thick. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is a Schmidt Hammer Used For?
The quality of concrete is judged mainly by its compressive strength, which directly affects the load-bearing capacity and durability of a structure. A rebound hammer gives a quick, non-destructive indication: a spring-driven mass strikes a plunger held against the concrete, and the distance it rebounds reflects the hardness of the surface layer. Because nothing is cut or broken, the same member can be tested at many points and re-tested later.
Typical uses include comparing concrete quality across columns, slabs and walls, locating weak or poorly compacted zones, and deciding where cores should be taken. For meaningful results, test on smooth, clean surfaces, take a set of readings at each location, avoid areas directly over reinforcement, and relate rebound values to crushing tests on the same concrete. It is a core item among test and measurement instruments for structural audits in India and abroad.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, supplies this N-type Schmidt concrete test hammer to engineering colleges, consultants, structural audit teams, dealers and importers in India and international markets. It is offered alongside other non-destructive and destructive concrete testing equipment, so a complete assessment kit can be sourced through one supplier. The company profile has more information.
Related Civil Engineering Lab Equipment
Rebound testing is most useful when combined with these methods and tools:
- Ultrasonic Pulse Velocity Tester — checks internal uniformity and defects to complement surface rebound values.
- Concrete cover meter — locates reinforcement so readings can be taken away from bars.
- Concrete Test Hammer — another concrete test hammer listed in the range.
- Automatic digital compression testing machine — crushes cubes or cores to correlate rebound numbers with strength.

Frequently Asked Questions
What does the Concrete Test Hammer Schmidt Hammer N-Type measure?
The Concrete Test Hammer Schmidt Hammer N-Type measures the compressive strength characteristics of hardened concrete non-destructively. It is used to control uniform concrete quality and detect weak spots in structures, giving a quick indication without cutting or breaking the member.
What is the minimum thickness of concrete that can be tested?
With the Concrete Test Hammer Schmidt Hammer N-Type, the test object should have a minimum thickness of 100 mm. Thinner or small elements may move or vibrate under the impact, which can distort the reading, so they need a different approach.
Does a rebound hammer replace cube or core testing?
No. The Concrete Test Hammer Schmidt Hammer N-Type gives a non-destructive estimate based on surface hardness. For reliable strength values, rebound readings should be correlated with compression tests on cubes or cores from the same concrete, then used to survey larger areas quickly.
How should readings be taken?
Hold the Concrete Test Hammer Schmidt Hammer N-Type perpendicular to a smooth, clean, dry surface and take several impacts at each test location, spaced apart and clear of edges and reinforcement. Record the orientation of the hammer, because the direction of impact also influences the rebound value.
Who supplies the Concrete Test Hammer Schmidt Hammer N-Type?
The Concrete Test Hammer Schmidt Hammer N-Type is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. It is available to colleges, laboratories, consultants, dealers and importers, and can be quoted with other concrete testing equipment.
Is a calibration certificate supplied with the hammer?
Please discuss any calibration or verification document needed for the Concrete Test Hammer Schmidt Hammer N-Type with us before ordering, so we can confirm what can be provided with the supply. Send the requirement through our contact page.
