PROCEQ CONCRETE TEST HAMMER TYPE NR CONCRETE TEST HAMMER Type NR Original Schmidt ASTM C 805 Type NR ASTM C 805 displays rebound values recorded on a strip chart. The most frequently used device method for non destructive strength testing of concrete structural components. Dimension 325 x 125 x 140 mm Weight 1.4 Kg with printout Concrete testing with the Original Schmidt test hammer is the most frequent used method for non destructive concrete testing worldwide. For every demand and specific test application Proceq offers the right concrete test hammer. Original Schmidt concrete test hammers are available in models with different impact energies in order to meet the needs to test a wide range of material types and sizes. Our types N NR L and LR are best suited and specially developed for assessing the quality and compressive strength characteristics of concrete with the range of 10 to 70 N mm2 1 450 to 10 152 psi . Versions incorporating paper chart recorders LR and NR can automatically register the rebound values on a paper strip chart. Proceq s type ND and LD Digi Schmidt test hammer measure the rebound values through an electronic method and allows the direct reading of the test results in digital form.

Concrete Rebound Test Hammer – Original Schmidt
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
Applications
Ideally suited for on-site tests of concrete
The concrete test hammer is suitable for testing a wide variety of concrete, mortar and rock, but also for testing metal castings
Handy for difficult to access or confined test areas (i.e. working overhead)
Assessment on young, soft concrete with mushroom plunger of the concrete test hammer, eg. asphalt strength testing
It can be even used for underwater applications
