Proceq Original Schmidt Concrete Test Hammer, Type N
Measuring range 10 to 70 N/mm² compressive strength (below 25 N/mm² type P is better suited). Impact energy = 2,207 Nm. Rebound values are read from a dial.
The quality of concrete is mainly judged by its compressive strength directly affecting the load-bearing capacity and durability of concrete structures. Proceq invented the Original Schmidt, the world’s first and now most widely used test hammer for analyzing the compressive strength of concrete properties.
The Original Schmidt will hit the concrete at a defined energy whereas its rebound is dependent on the hardness of the concrete and is measured by the instrument.
The Original Schmidt is available in models with different impact energies, each test hammer designed for a specific test application, in order to meet the needs of the customers to investigate a wide range of material types and sizes, such as bridge decks, thin walls, cast stone components or small components.
Type N Original Schmidt: Rebound values are read from a scale for subsequent calculation of the mean. Compressive strength values can be read from a conversion diagram
