Concrete Rebound Test Hammer - Original Schmidt Type N
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 is
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.
Features
- 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
- Type NR Original Schmidt: Rebound values are recorded as a bar chart on a paper strip which has a capacity for 4’000 test impacts
- Type L Original Schmidt: Handling equals type N, but the type L offers an impact energy three times smaller
- Type LR Original Schmidt: Handling equals type NR, but with impact energy three times smaller. The LR also features a paper strip for recording up to 4’000 test impacts without reloading
