Hammer Test Proceq Original Schmidt
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.
Testing the compressive strength of a prefabricated
concrete girder. Rebound values are recorded by an assistant who will calculate mean values and read
compressive strength values from a conversion
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
