The NOVOTEST MSh Concrete Rebound Hammer is a precise, reliable tool for non-destructive testing of concrete and other building materials. By impacting a plunger on the surface and measuring the rebound height, it provides a direct correlation to the material’s strength, which can be interpreted using the supplied calibration charts.
Originally developed by engineer Ernst Schmidt, the rebound hammer method remains one of the most widely used techniques for assessing concrete strength worldwide. Its operation is simple yet highly effective: the plunger strikes the surface with a predetermined energy, and the rebound height is proportional to the material’s strength.
The NOVOTEST MSh is designed for ease of use, robust performance, and high measurement accuracy, making it ideal for field testing. It meets international standards including:
-
ASTM C805 – Testing Concrete Compressive Strength
-
ASTM D5873 – Rock Testing
-
DIN 1048, Part 2
-
ENV 206
-
EN 12504-2
-
ISO/DIS 8045
Models & Applications
The NOVOTEST MSh series offers multiple models to suit different testing needs:
| Model | Impact Energy (J) | Measurement Range (MPa) | Minimum Thickness (mm) | Typical Use |
|---|---|---|---|---|
| MSh-225 | 2207 | 10 – 60 | ≥70 | Standard model for concrete ≥70 mm thick and large rocks |
| MSh-75 | 735 | 10 – 60 | 50 – 100 | Ideal for bricks, concrete products <100 mm thick, and low-strength rocks |
| MSh-20 | 196 | 1 – 25 | ≥30 | Designed for mortar testing in brick masonry |
All models are non-destructive, ensuring the integrity of tested structures.
